DNA is the key for our genetic apperance. DNA is a double stranded and is formed by blocks of nucleotides. Nucleotides each consist of three parts. A phosphate‚ a pentose sugar (deoxyribose) and a nitrogenous base. The nitrogenous bases carry the information for proteins which are needed in our body to function properly. Proteins are made according to the nitrogenous bases. When DNA replicates‚ it’s extremely important that it is copied exactly. If it’s not the protein which is produced according

DNA is the primary genetic material that makes each individual different. DNA is the molecule that makes up chromosomes each pair of chromosomes contains DNA from one parent. DNA is found in the nuclei of eukaryotic cells and prokaryotic cells in living organisms. DNA is so important it is unable to leave the nucleus therefore the body makes RNA to carry information out into the cytoplasm. The three major components of DNA nucleotide monomers are phosphate‚ 5 carbon ring sugar (de-oxyribose) and

Something new was also used in this case‚ dog DNA. During the investigation‚ police learned that Taylor had been walking his dog around the time Leanne’s body was placed in the woods. Forensic examiners found dog hairs on Leanne’s body. The dog hair DNA sample was sent to a university in Texas. It produced a partial profile for a dog. However‚ this was not able to be used against John Taylor because he had killed this dog before the evidence was found. The dog had been buried‚ in Taylor’s back garden
