DNA. Computer representation of a segment of the beta-deoxyribonucleic acid (B-DNA) molecule. This structure contains the inherited instructions necessary for the development of life. Atoms are colour-coded: phosphate (yellow); oxygen (red); nitrogen (blue); carbon (pink). The DNA molecule is composed of two strands twisted into a helical shape. Each strand of DNA consists of nucleotides joined in a row like central rungs in a ladder; a nucleotide consists of a sugar,a phospate group,and one of 4 different bases. There are twelve such base pair segments represented here. The arrangement of base pairs along the molecule | |
