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

DNA REPLICATION At the replication origin DNA helicase attaches to a strand of DNA and begins to break apart hydrogen bonds in order to unravel a section of the double helix. The section of DNA that is unwound is called the replication bubble and the “Y” shaped sections are called the replication forks. In order to stop the unwound section from binding back together‚ single strand binding proteins react with the single strand portions on the DNA causing them to stay separated. Although the leading
Premium DNA DNA replication
DNA replication is a biological process that occurs in all living organisms and copies their DNA. DNA replication during mitosis is the basis for biological inheritance. The process of DNA replication starts when one double-stranded DNA molecule produces two identical copies of the molecule. Each strand of the original double-stranded DNA molecule serves as template for the production of the complementary strand‚ a process referred to as semiconservative replication.
