WebDNA ( deoxyribonucleic acid) is the genetic material of living organisms. In humans, DNA is found in almost all the cells of the body and provides the instructions they need to grow, function, and respond to their environment. When a cell in the body divides, it will pass on a copy of its DNA to each of its daughter cells. WebDNA is made from a four-letter code made of A, T, G and C. The DNA bases pair together: A-T, T-A, G-C and C-G. DNA is arranged in a double helix structure.
