Light micrograph of human DNA. The DNA strands of various length have been precipitated in alcohol from a suspension of lysed (burst) blood cells. Deoxyribonucleic acid (DNA) is the material of inheritance of most organisms. Its double-helix structure consists of two strands of nucleotides. A nucleotide consists of 3 subunits: a sugar,a phosphate group & one of four different bases: adenine (A),thymine (T),guanine (G) & cytosine (C). Genetic information is determined by the sequence of these bases along the molecule. Magnification unknown | |
