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 Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. A molecule of DNA is made up of long chains of polymers and monomers called nucleotides. Those chains‚ two in particular that compose a strain of DNA‚ are formed by the grouping of nucleotides into polynucleotides. A nitrogenous base‚ a sugar‚ and a phosphate group make up the composition of a nucleotide. In the case of DNA‚ the four nucleotides that are found along the chain of DNA are thymine (T)

Comparison between Carrie Chapman Catt and Thomas Paine In 1917‚ Carrie Chapman Catt addressed the United States Congress regarding women right to vote. She relied on ethos and logos to make her argument rather than emotional appeal. In 1776‚ Thomas Paine addressed the whole population of the thirteen colonies regarding the independence of the colonies from Britain. He also mainly relied on ethos and pathos to make his argument. Catt claimed that women suffrage was inevitable while Paine’s claimed

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

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA molecules are composed of two strands that form a helical ascending spiral. They fit together like the opposing teeth of a zipper and are held together by weak interactions called hydrogen bonds. These two strands is a long string of subunits called nucleotides‚ each attached to the one immediately about it and the one immediately below it to form a long chain. Each

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. Cellular proofreading and error-checking

DNA is a polymer‚ which is a chemical compound or a mixture of compounds consisting of repeating structural units. These repeating structures are created through polymerization. The monomer‚ meaning one part‚ units of DNA are nucleotides. Each nucleotide consists of a five carbon sugar‚ also known as deoxyribose‚ and nitrogen containing base attached to the sugar
