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 lack ...

Lab 1: Ethical Issue in the Movie Gattaca. The epicentre of ethical issues in the movie Gattaca is the manner in which an individual ought to be judged. Should it be by the genetic composition one is born with or by the character traits, personality attributes and ambitions chosen by an individual? Vincent is born with genetic weaknesses that could result in ailments in the future. His genetic composition denies him access to his dream job despite the fact that he achieves the required grades in school and is a strong and athletic young man. As a result, Vincent designs a plan to ...

- If K65R and D113E are conserved mutations, what type of mutations are Q151M and Q151N. They are non-conserved is not the correct answer.
K65R and D113E being conserved mutations implies that even after undergoing mutations they retain the original properties. There functionality remains almost the same. On the other hand, Q151M and Q151N, mutations will result in a change of their initial properties or additional functions may be gained in the process of mutation.
- The K65A RT mutant had a reduction in RT activity. Explain the reasoning behind this phenotype
In the cell, the presence of ...

Question 1

The type of bloodstain evidence at the scene is a cast off pattern. According to Becker (2005), a cast-off pattern normally results in blood striking nearby surfaces such as walls, floors and ceilings. A cast-off pattern indicates that a blunt force trauma to the head. The large wound on top of the head is indicative of repeated use of the blunt force weapon on the victim.
The first step in the documentation process of the room would involve conducting an initial scan of the room to ascertain the evidence present. This would then be followed by photographing of the scene in ...

- Describe the phases of meiosis II
Meiosis II has 4 phases, prophase, metaphase, anaphase, and telophase. At the end of meiosis I, microtubules move each member of the centriole pair to an opposite spindle pole in both daughter cells. During prophase II, the microtubules attach to the chromosomes causing them to recoil and shorten. During metaphase II, the microtubules, duplicated chromosomes, and motor proteins, interact in a manner that positions all the duplicated chromosomes halfway between the 2 spindle poles. During anaphase II, the connection between the 2 sister chromatids of every chromosome breaks and each of the ...

Introduction

Tooth development involves a complex process whereby teeth are formed from embryonic cells, and then eventually mature after erupting as evident in the mouth (Eckhardt, Jágr, Pataridis, & Mikšík, 2014). The development usually originates from mesoderm and ectoderm. At the ectoderm found in the oral cavity, there is the development of enamel and other tissues also come from associated mesenchyme. All teeth don’t develop at the same time, but rather in stages (Eckhardt, Jágr, Pataridis, & Mikšík, 2014). First buds are always observed in the region of anterior mandible, followed by anterior maxillary area then finally ...

Abstract

In the last century, the knowledge of molecular biology has increased, opening new opportunities for addressing different diseases that have been affecting all populations. Before, genome and proteomic studies were seen as complicated field due to inability to get significance understanding of disease components at the molecular level. However, with the expansion of molecular biology, different techniques and tools have been developed to aid diagnosis and treatment of diseases. In this study, these tools have been investigated to understand how the knowledge on molecular diagnosis helps in detection and treatment of diseases. This study focused on the application of ...

Question 2

Non covalent bonds attach the paired bases that compliment each other. The bond serves a strengthening feature in attaching the complimentary pairs. The bases that are complimentary in the bases of a DNA are G= guanines, A= adenines, C= cytonines and T= thymines. The bonding process of bases is done when G bonds with C, T bonds with A. This is the rule for bonding of the DNA bases. These are strongly found between the base and nucleotides that are completed when the four bases interact to make a adenosine monophosphate (Audesirk, et al., 2011).

Sometimes Forensic Casework items consist of less than 100 picograms (pg) of template DNA which, if we assume 3.5 pg of DNA per haploid cell, can be equated to approximately thirty haploid cells or fifteen diploid cells are termed as LCN DNA (low template DNA or LT DNA). (Gill 17)
Such low copy number (LCN) samples exist due to several factors like damaged or degraded DNA, oligozoospermia or aspermic perpetrators or extended interval post coital samples, where there is loss of sperm over time because of the effects of drainage or host cell metabolism. From crime scenes, Trace ...

Methodology

The first step involved ligation of digested polymerase chain reaction (PCR) products into pGLUX1 proteins. Thereafter, the resultant proteins were transferred onto nitrocellulose filter membrane (NCF). This is where the ligation reaction was used to transform E. coli XL10-gold cells. Thereafter, specific cells were selected to undertake DNA plasmid isolation through being subjected to 200 volts for 50 minutes. In confirming complete ligation of the cells, restriction digest using XhoI and KpnI enzymes were used. The digested products were then subjected to agarose gel electrophoresis. In this case, the transfected culture was grown at 37°C under drug selection ...

Introduction

The collection of bacterial, archaeal, eukaryal and viral microbes in surface waters, oceans soils and wastes together constitute the environmental microbiome. This microbiome is vital to humans and the environment in several ways including but not restricted to nutrient recycling, biotechnological application in the food and beverage industry and genetic engineering technologies. Nonetheless, pathogenic microbes can invade and grow within other organisms causing disease (Egli and Koster).
Different strategies have been used to define microbial community structure across microbial ecosystems. Taxonomic classification based on morphologic and physiological traits of cultured microbial communities is no longer attractive since the ...
