DNA replication

four nitrogen bases shown in Model 1 are Adenine, Thymine, Guanine, and Cytosine. 2. a) I pointed at a single nucleotide on the ladder model of DNA, on the worksheet. The nucleotide included phosphate, nitrogen-containing base, and the deoxyribose sugar. b) The nitrogen-containing base(s) and hydrogen bond(s) make up the rungs of the "ladder" model of DNA. c) The phosphate and the deoxyribose sugar are the parts of the nucleotide(s) that make up the sides (backbone) of the "ladder"…

large effect on the population is tuberculosis (TB). Tuberculosis is caused by the spread of a bacterium and if the bacterium is not treated properly, TB can be fatal. With the use of antibiotics, such as streptomycin, the fundamental process of DNA replication, transcription, and translation can be altered to the advantage of curing TB. Tuberculosis is an infectious disease that is spread via the air. According to the World Health Organization, tuberculosis is estimated to kill 1.5 million…

nucleus that entraps the DNA unlike the prokaryotic cell that lets it be free. A prokaryote is also known as bacteria. The DNA roams freely inside of the cell. Eukaryotic cells are large meanwhile prokaryotic cells are much smaller. There are many differences about the prokaryotes and eukaryotes cells. The DNA replication of a eukaryotic cell would be two chains held together by H bonds. The nitrogenous bases that eukaryotes have are adenine, thymine, guanine and cytosine. DNA structure…

A cancer cell will ignore the checkpoints that's regulating mitosis, cancer begins when a single normal cell is transformed from a regular cell to a cancer cell. This is often due to a change in function or a DNA mutation that occurs in one of the several genes that function to control growth. The first unusual feature is that cancer cells are frequently immortal. Normal cells can only divide about 50 times and then die, but cancer cells can go on dividing frequently…

It can be argued that “… the origin of life is the origin of replication” (Lane, 2010). This statement proves to be correct to a certain extent as if there were to be any mutations within the stages of replication, the life created could have abnormalities which may decrease quality of life experienced. Sickle cell anaemia is a hereditary form of anaemia in which a point mutation causes the formation of haemoglobin which distorts the erythrocytes into a sickle-shape (Appendix 1). The sickle…

Describe the chemical structure and function of DNA DNA is a fundamental molecule responsible for the growth and maintenance of the human body. Since the discovery of DNA and its double helix structure though the Watson-Crick Model, there has been a significant increase in the understanding of human disease and development of effective treatment. DNA’s specific chemical structure allows it to carry out its function which therefore maintains our survival. Deoxyribonucleic acid is a…

1. DNA Structure and Function DNA is the type of organic compound that stores the genetic information in a living organism. DNA is made up of two strands of nucleotides, which include a phosphate group, five carbon sugar, and a nitrogenous base. Each individual strand in held together by strong covalent bonds (a bond formed as a result of the distribution of electrons between atoms). The two strands are then joined to each other by hydrogen bonds between complementary bases. There are four…

It consists of an icosadeltahedral capsid that houses the dsDNA, a proteinaceous tegument, which surrounds the capsid and contains proteins that aid viral replication, and an envelope with glycoproteins. To gain entry into the human host cell, viral glycoprotein C binds heparan sulfate or chondroitin sulfate on human cellular glycoproteins. Next, viral glycoprotein D, which is associated with glycoprotein H and…

this study used mitochondrial DNA sequence data in hopes of showing that A. geoffroyi and another spider monkey (Ateles fusciceps) form two separate monophyletic groups. The only other study to use molecular data for determining phylogeny in Mesoamerican spider monkeys was the Collins and…

The DNA quantitation is conducted to determine the amount of DNA is contained within a given biological sample. Biological samples are sent to the laboratories with the intention of developing DNA profile. It is important for the high quality development that the analyst first determines the quantity of DNA present in a sample. If there is too much DNA present, this can cause off-scale data in the final detection in a sample. Off-scale data can be littered with artifacts and extra peak…
