DNA stands for Deoxyribonucleic acid. DNA is the polymer that makes up our chromosomes and genes. Offspring receive DNA from their parents, via the sperm and egg cell in sexually reproducing individuals, or from the single parent if reproducing asexually. DNA is able to replicate itself, thus insuring that cell division as well as reproduction can occur and life can continue. The subunits of DNA are called nucleotides, consisting of a phosphate group, a sugar--deoxyribose and one of four nitrogenous bases--adenine, guanine, cytosine and thymine. The DNA molecule has the shape of a double helix. See the link below which is my original powerpoint for more information.
