Understanding DNA Have you ever wondered how you got red hair or blue eyes? Well all that has to do with your genes. To have different genes you have to have a deoxyriboncleic acid or DNA for short. Without Dna everyone would and everything would look the same and that would make life really confusing. Your DNA has a very important role in life. Its most important role is to give everyone character. Every Dna chromosome is made the same according to species. They are made up of two strands of Nucleotides

General Biology DNA and RNA Deoxyribonucleic Acid and Ribonucleic Acid • DNA is deoxyribonucleic acid. It is located in the nuclei of cells‚ which make up the body. Consequently‚ DNA can be considered as one of the building blocks of the body. Where is DNA found? DNA‚ or deoxyribonucleic acid‚ is the hereditary material that lies within the nucleus of all cells in humans and other living organisms. Most of the DNA is placed within the nucleus and is called nuclear DNA. However‚

What is DNA? DNA‚ or deoxyribonucleic acid‚ is the hereditary material in humans and almost all other organisms. Most DNA is located in the cell nucleus (called nuclear DNA)‚ but a small amount of DNA can also be

Second meaning is being the primary cause of something and so able to be blamed or credited for it. Responsible

reliability of DNA forensics. In 1984‚ British geneticist Alec Jeffreys of the University of Leicester discovered an interesting new marker in the human genome. Most DNA information is the same in every human‚ but the junk code between genes is unique to every person. Junk DNA used for investigative purposes can be found in blood‚ saliva‚ perspiration‚ sexual fluid‚ skin tissue‚ bone marrow‚ dental pulp‚ and hair follicles (Phillips‚ 2008). By analyzing this junk code‚ Jeffreys found certain sequences

DNA‚ or deoxyribonucleic acid‚ is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA)‚ but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). The information in DNA is stored as a code made up of four chemical bases: adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). The order‚ or sequence‚ of
