Essays on Sequence

There are several mathematical formulae that mathematicians and scientists have come up with over time. These mathematics formulae solve or address several issues or problems in the real world or mathematical and scientific field. One of the well-known mathematicians is Augustin Louis Cauchy. He is credited for coming up with the Cauchy sequence (the Cauchy sequence is named after him). This paper explores the Cauchy sequence, explaining its nature, form, application, and other related aspects of the sequence. What is Cauchy sequence? This is a sequence whose elements become arbitrarily close to each other in the course of progression ...

The cDNA that was used in the experiment is the transfer tRNA. The coding region refers to the gene portion (DNA or RNA) that has axons in it and they code proteins. It’s also known as the coding sequence or the coding DNA sequence. The coding region sequence is surrounded near the 5th end of the start codon and the 3rd end with a stop codon. Therefore, the total addition of the genome of a living thing consists of the gene coding regions. The identification of the cDNA coding region sequence is not straight forward because the existing ...

Q1. Describe the three main layers of the Sun’s interior.

The three main layers of the Sun’s interior are the core, the radiative envelope and the connective envelope.

The core is the center of the Sun, with a density of 150 g/cc and a temperature of 15 million K. This is the region where high energy fusion reactions take place and energy is produced. The energy produced is mainly in the form neutrino and gamma rays, which are actually high energy protons which travel several light years and supply energy to the Earth and other planets. The energy produced in the core then radiates outwards through the radiative zone. The temperature here is quite lower, about ...

1. When placed on an agar slab and incubated at 30°C for 2 days, a single yeast cell proliferates into a colony with a diameter of 2 mm containing 108 yeast cells. If the cell has a functional Ade2 gene (Ade2+), the colony will be white; if Ade2 is non-functional (Ade2–), the colony will be red. You take a strain with a mutant Ade2– at the regular chromosomal position (red colonies) and insert a second, functional Ade2+ gene near the telomere. You find that the colonies are a mixture of red and white patches or sectors. Figure 1 ...

Indian’s populist film industry, known often by its colloquial term Bollywood, often uses song and dance not only as a work of spectacle within the body of the film, but as a way to significantly discuss the narrative and characters of the film itself. Songs and dance sequences provide opportunities for the characters to explore their jubilation, sorrow or consternation, among a plethora of other emotions, and offered significant platforms for the stardom of Indian film stars, who would often also be significant presences in the film and culture scene in India. One of the most significant Bollywood ...

It is at the Sun’s Core that thermonuclear reactions occur because of the enormous temperature and pressures. Second, the Sun’s Radiation Zone or the middle interior part, where energy travels ...

Malaria is a tropical disease that has claimed many lives over the numerous centuries gone by (reference). It usually caused by the genus Plasmodium. The vector for this parasite is a female Anopheles mosquito which transmits the pathogen through bite (reference). One of the major challenges in disease vectors is insecticide resistance. Vector-borne diseases are usually a burden in developing countries because it is not easy to reduce/control disease. In many parts of Africa, Anopheles gambiae has developed resistance towards pyrethroid insecticides which is used to control the malaria vector (Kumar, Dudley, 2007). It is feared that there are high chances of reduction in efficiency of bednets which are treated using the same insecticide. Sprays containing pyrethroids will also be useless if used because it will not have any effect on the vector since it has developed resistance. ...

The variability of stars existing within our universe represents diversity and uniqueness. Humanity may not observe the whole life of a single star, however, techniques have been proposed to study the stars. We have different ways how to measure a star's temperature, age, and mass even, even though it seems impossible. The said variability of stars is key to the measurement of a star's characteristics. The existence of variable stars suggests that stars change on a time interval, unfortunately, too long humanity cannot observe. Nevertheless, humanity have developed a way of understanding the stars through their variability. Needless to ...

Abstract

Proteins are made up of amino acids and have major structural as well as functional roles in the body. Amino acid chains are synthesized from DNA sequences through transcription and translation. Proteins become fully functional only after co-translational or post-translational modification of the amino acid side chains and folding into appropriate three-dimensional conformations. Even slight changes in the DNA code could drastically alter the protein folding, alter its functioning, and eventually lead to certain diseases. Inherent cellular repair mechanisms, protein degradation pathways and molecular facilitators such as chaperones try to keep proteins in their native, stable conformation by acting ...

Introduction

Genetic evolution refers to change(s) in inheritable traits occurring across succeeding generation of organisms. The change (evolution) is responsible for the diversity at all levels including the molecular level e.g. genetic variations, individual organisms in the same species (intra-species variations) and among species (interspecies variations). It is believed that all organisms emanated from common ancestry about 3.7 billion years ago and then evolved over time to the present biodiversity. Therefore all organisms have some shared traits at the morphological and molecular level with the species sharing a more recent ancestry having more similar traits. The process of evolution ...

Takashi Miike's 1999 film Audition is an artful yet horrifying tale of a mild-mannered widower (Ryo Ishibashi) who, in his attempts to find a new wife, falls for a young woman Asami Yamasaki) who is far more than meets the eye. Miike's signature dreamlike mise-en-scene, complete with moody and atmospheric cinematography and strong, vulnerable performances from both leads, creates a twisted romance/revenge film that strongly addresses issues of gender roles and divisions within relationships, particularly as they are applied to Japanese culture. The film explores and critiques notions of romanticism normally found in modern romantic dramas, as the representation ...

Introduction: Genetic mutations are associated with changes in the genomic sequence that are the main cause of diversity among organisms. The changes in genetic sequence can occur at any instance and are known to have different consequences. Mutations are often associated with a change that affects the nucleic acids in most organisms. Nucleic acids are considered as the building blocks of DNA. On the other hand, DNA are associated with the storage of information that is transferred to the offspring during reproduction. Mutations are associated with diversity and considered as an essential part in evolution. Genetic mutation is considered ...

Dear Grandma,

Our body has tissues and organs that are made up of different types of cells. Each cell contains the deoxyribonucleic acid also known as DNA. This double-stranded DNA is made up of 4 chemical molecules also known as bases: adenine (A), guanine (G), cytosine (C) and thymine (T). In the DNA, A always pairs with T; C always pairs with G. These strands are nothing but sequences of these bases that run really long. So typically a short sequence of DNA if written down in English will read:

Shelby, Legree and St Clare were once slave owners of tom, and they had an important contact on Tom in that both played a big role in building Tom’s faith and his hopes in God whenever he started doubting himself. Likewise, it’s clear that at times Tom got on their nerves, by the way he reacted but none of them manages to change Tom’s personality in a negative way. Both St Clare and Shelby are kind and honest to Tom all through; they treat him in a genuine manner despite him being a slave (Henson, 21) ...

Abstract

Trichomonas gallinae, a flagellated protozoan, adversely affects the avian livestock, particularly the columbids. It causes an infection called necrotic ingluvitis and the disease can range from asymptomatic to lethal. The parasite affects the anterior gastrointestinal tract of the bird, forms granulomatous lesions, and blocks the oesophagus, making the bird starve, thus leading to death. The virulence of the strain varies with some strains causing up to 75% mortality. In UK, the infection was first recognized as an emerging infectious disease of British finches in summer of 2005. The sick dead birds exhibited signs of malaise such as lethargy and ...

Introduction

The emergence of real-time polymerase chain reaction (PCR) assays was much of a relief in the medical field especially given the fact that this model offers the most accurate way in the process of determining false-negative outcomes (Burggraf & Olgemoller, 2004).This ideology also finds support in the works of Nolte (2004) who asserts that, following the discovery of PCR and its application in a clinical setting, it has become possible to use nucleic acid amplification methods as transitions from research to clinical laboratories. This makes it possible to have a wide array of application in addressing issues relating to ...

Telomerase also known as telomere terminal transferase is a type enzyme in all vertebrates that extends Die ribonucleic acid sequence by repeating TTAGGG to the Die ribonucleic acid terminal strands in the region known as the telomere. It is found in adult germ cells, fetal tissues, and tumor cells. Telomere is the region of repeated nucleotide, which is made up of non-coding Die ribonucleic acid material. The region prevents loss of vital Die ribonucleic acid from chromosome terminals. This results to only a hundred to two hundred nucleotides being lost each interval the chromosome is duplicates, thus no damage ...

Introduction

Biology is broad and therefore embraces various topics in life that concern living organisms. Micro biology for instance deals with the study of very small organisms that are able to reproduce and sustain their generations. This is where the study of prokaryotes comes into the scene. The contrasting organisms to prokaryotes are referred to as eukaryotes. Contrary to prokaryotes, eukaryotic organisms have complex cell structures. Biology tends to full describe the complete nature of these organisms, their feeding habits, how they reproduce and where they thrive best, that is, their habitats.

Prokaryotes are single celled organisms whose cells ...

Pythagorean triples have been first mentioned in the second millennium BC by Babylonians. The triple consists of three positive integers a, b and c, which are related to each other by the Pythagorean theorem a2 + b2 = c2. Thus, they represent the length of the three sides of a right Pythagorean triangle. Primitive Pythagorean triples are the triples, which are co-prime, therefore the only common positive divisor is 1.

One of the methods for generating Pythagorean triples was proposed by Leonardo of Pisa. His technique uses consequent odd integers, such as 1 and 3, then add them together in order ...

Background

Early scientists and nutritionists believed that the most vital nutrient in living organisms, for building and maintaining the body was the protein. The role of proteins as enzymes came into existence several years later. This was around 1926 when experiments showed that enzymes were proteins. Insulin was the first protein to be sequenced. Hemoglobin was the first structure of proteins to be resolved. Myoglobin was then resolved later.

X-ray diffraction analysis (X-ray crystallography) led to the determination of the structure of the proteins (three-dimensional structure). The purification of proteins can be made possible from cellular compounds. ...

Given Sequence:

The question is finding the set for the next dates. It is obvious that the dates have an alternating 3 and 4 difference of interval. You can guess if this problem is all about an arithmetic series or a geometric series.

As for an arithmetic series, you need to use this equation:

where a1 is the first number of the sequence,d is the common difference, n is the number of the term to find. But before using this equation, you need to evaluate if the series you have has constant d (difference). Let us assume that the allowable series to be solved is the in the column and the ...

In the wake of the second world war and with the entry into what would come to be known as the “nuclear age”, the world knew that nothing would be the same in the second half of the 20th century. Arguably, nobody felt the dawn of the nuclear age greater than Japan following the devastation and chaos caused by the Hiroshima and Nagasaki bombings. First-hand accounts of the bombings were frightening; people screaming, fleeing, desperate to find cover, while a blinding light and a sudden blazing heat suddenly filled the air, followed swiftly by an ominous roar, a steady ...
