DNA. Model of part of a molecule of DNA (deoxyribonucleic acid),the genetic material found in all living cells. This is the most common form,beta DNA,which spirals clockwise when viewed from above. DNA encodes the hereditary characteristics of living organisms and is responsible for all hereditary traits. It consists of two strands wound around each other in a double helix. The strands each have a sugar-phosphate backbone connected by paired nucleotide bases. In DNA these bases are cytosine,guanine,thymine and adenine. It is the sequence of these four types of bases which determines the unique genetic code of an individual | |
