DNA

The importance of noncoding DNA sequences Since the completion of Human Genome Project in 2003, it was found that more than 98% of human genome is occupied by noncoding DNA sequences (Genome.gov, 2003), existing between genes and as introns within genes (Figure-1). In genomic, noncoding DNA regions are defined as the sequences of an organism’s DNA, which do not code for proteins. Although it has been known for decades that some of these sequences code for noncoding RNAs that…

DNA makes proteins. DNA is stored in the nucleus and contains phosphates (a phosphate includes nitrogen bases). DNA is made up of these phosphates, but, in making polypeptides, or a protein, the nitrogen bases are the most important in his process. To make a polypeptide, the helicase unzips the double helix figure, making two rows, or strands, which are one side of all of the nitrogen bases. Floating nitrogen bases string the opposite of these sides, to make an original copy, but leave, ending…

it both current and informative. It serves a great purpose providing various benefits. However, the use of technology can also raise some controversy. The advancement of DNA technology is imperative and it has significantly changed the legal system in the way cases are questioned, investigated and solved. On the other hand, DNA sampling raises issues involving privacy and the violation of human rights due to its personal, unique makeup and the fact that it is stored in a database. The…

Franklin: Dark Lady of DNA, by British biographer Brenda Maddox. Brenda Maddox does an admirable job writing the untold story of an admirable Jewish woman, Rosalind Franklin, who tries to make her mark in science. Brenda Maddox’s biography tells a lot more than a sincere story of bullying, harassment, and gender discrimination. Rosalind Franklin is best known for her…

The uses of Mitochondria DNA (mtDNA) is necessary in forensic because the DNA provides forensic science with valuable tools when investigating criminal cases, missing person’s cases and mass disasters (Sandhyarani, 2011; National Institute of Justice, 2013). MtDNA is a small double strand, circular molecule of 16569bp and it contain 37 genes located in a circular genome located outside of the nucleus. There are 2 rRNA, 22 tRNA and 13 polypeptides (Taanman, 1999; Webb, 2008). Most human cell…

Reference, 2017). DNA can be found in all cells of the body except red blood cells and can be collected from hair follicles, blood, skin, bodily fluids, bone marrow, tissues etc (GHR, 2017). In criminal cases, DNA is used as evidence to prove whether a person was connected with a crime. If a person’s DNA is found at a crime scene, they become a suspect in an investigation. The use of DNA as evidence has challenged traditional legal principles and processes. However, the analysis of DNA has not…

INTRODUCTION: What is DNA? DNA is a deoxyribonucleic acid, which is a self-replicating material that is present in just about all living organisms as the top chromosomes. DNA Isolation is the development of purification of DNA from a sampling applying a mixture of physical and chemical methods. Isolation is a routine process in molecular biology or in molecular analyses. Materials: • Electrophoresis chamber • Gel casting trays • Sample combs • Ethidium bromide • Loading buffer •…

The myriad ways that DNA is now used in solving crimes, medical purposes and tracing family history, makes the the benefits of DNA one of the most magnificent discoveries of the 20th century. In this essay, you will learn upon many about DNA subjects, including matching, DNA analysis, due process and inclusion versus exclusion. DNA has come a long way, dating all the way back to the 16th century where Chinese businessmen used their thumb print as a means of access to money. In 1987, Tommie Lee…

World War II is coming to an end and the race begins to discovered the structure of DNA. It’s May 1st, 1952 in a London lab an x-ray camera is clicking off 100 hour exposure of something called DNA. When developed this photo will show the structure of DNA. This photo will explain the blueprint of all life, and how DNA is passed on from generation to generation. Francis Crick and an american scientist James Watson will be in the race for discovery of the century, along with 31 year old British…

1) The major difference between these two is that the RNA viruses have RNA in their genome while the DNA viruses have DNA in their genome. Both the DNA and RNA cannot be found in the same virus. RNA virus first adsorbs to the host cell surface. Then the attached virus fuses with the endosome membrane. Unlike RNA viruses, DNA viruses pass their DNA into the nucleus of the host cell and not into the cytoplasm of the host cell. 2) Lysis: refers to the breaking down of the membrane of a cell, often…
