Extracting DNA from the Bacterium Escherichia coli Introduction Deoxyribonucleic acid is contained in all cells. The mental synthesis of DNA makes gene transmission possible. Since genes are segments of DNA, DNA must(prenominal) be able to make exact copies of itself to enable the close generation of cells to receive the same genes. The DNA molecule looks standardized a twisted ladder. Each side is a chemical chain of alternating phosphate and deoxyribose sugar molecules. The steps are form by bonded pairs of purine-pyrimidine bases. DNA contains four such bases the purines adenine (A) and gravitational constant (G) and the pyrimidines cytosine (c) and thymine (T).
The RNA molecule, markedly similar to DNA, normally consists of a single chain. The RNA chain contains ribose sugars instead of deoxyribose. In RNA, the pyrimidine uracil (U) replaces the thymine of DNA. DNA and RNA are do up of basic units called nucleotides. In DNA, each of these is composed of a phosphate, a deoxyribose sugar, and either A, T, G, or C. R...If you want to get a full essay, order it on our website: Ordercustompaper.com
