Essays on Prokaryotes

Hi. I am streptococcus bacterium. I belong in the family Streptococcaceae. My name streptococcus means twisted berry which describes mu characteristic grouping in chains which looks like a string of beads. I am nonmotile and gram positive. I am a common type of prokaryote. I can cause various diseases in humans and animals. If I were to look for a partner, I want something that thrives in the anus, pharynx, and skin because these are my carrier state. I can also look for a partner in raw milk and contaminated foods like eggs and milk. For me, the dirtier ...

Bacteria refer to the regnum of prokaryotes (Sundararaj, Mudaliar, Anthoniraj, Kannan, Muthukaruppan). For the current moment, it accounts for more than ten thousand kinds of bacteria. The bacterium is recognized as one of the most ancient of living organisms, arising about 3.9 – 3.5 billion years ago. Bacteria have the substantial variation in the ways of metamorphic and energetic metabolism. Thus, autotrophs can synthesize all necessary organic molecules from non-organic compounds, whereas heterotrophs demand active organic compounds to transform them. The biggest degree of heterotrophs belongs to intracellular parasites. They are called saprophytes (Sundararaj, Mudaliar, Anthoniraj, Kannan, Muthukaruppan) and can ...

There are six stages in the life cycle of a mitotic cell which include interphase and cytokinesis. The mitosis stage is divided into four other sub stages. Mr. Interphase performs various functions such as the cellular respiration, photosynthesis and protein synthesis in preparation to undergo the Mitosis stage. Mr. Mitosis has four witnesses, Prophase who helped nuclear membrane disappear into the genetic material. The other witness, Metaphase, makes the alignment of the chromosomes. Anaphase helps in centralizing the chromosomes and changing them from being x-shaped (Rieder, 17). The last witness created the new component of nuclei with their new ...

Cells are the building blocks of many structures in biology. In their most basic classification, there are prokaryote and eukaryote cells. These two cell types differ in their structure. Prokaryotes typically consist of ribosomes, a cell membrane, and nucleic material. On the other hand, eukaryotes contain membrane-bound organelles, such as Golgi apparatus, lysosomes, a nucleus, and endoplasmic reticulum. Both types of cells also have nucleic acid as a form of genetic material. The prokaryote has circular DNA which is not associated with histone proteins; whereas the eukaryote has linear DNA with histone proteins present to help organize and protect ...

1. DNA in forensic science: DNA contains the genetic code of a person. The genetic information stored in the DNA, is coded in the form of nucleotide sequence. The nucleotide sequence is formed by four fundamental nucleotides: A, T, G, C nucleotide, that formed a polymer in a set order. A typical human DNA, has 3 billion nucleotide bases. The DNA sequence is 99.8% identical in all human beings and is only 0.2% dissimilar. This dissimilarity is the basis for identification of the suspects in forensic medicine. No two human beings can have a DNA that is 100% identical. ...

Codominant traits exist when two different alleles for a genetic trait such as flower colour, and hair texture are both expressed. The expression of codominance infers a relationship between two types of a gene. In codominance, the phenotypes of both alleles inherited from the parents are expressed ("Codominance - Glossary Entry", 2016).

Genetic expression feather colors in purple penguin ("Basic Principles of Genetics: Probability of Inheritance", 2016).

With the order of dominance as pd>pm>pl>pvl a 1 dark: 1 medium ration of phenotype among the baby penguins is expected. Marfan Syndrome is a genetic disorder that exhibits variation among affected individuals. The range of phenotypic severities is an example of variable expressivity. ...

The field of microbiology was very limited until the discovery of the microscope, though it did exist in a very practical sense. Though scientists were ultimately wrong about what actually carried and transmitted the plague, for example, they were correct in hypothesizing that it came from an outside source. Between then and now, the microscope was developed, and has been improved upon more and more. Now we have a great classification scheme for prokaryotes (assuming bacteria). It follows the standard domain, kingdom, phylum, class, order, family, genus, and species. The standard for most eukaryotes is also the same for ...
