Similar term(s): deoxyribonucleic acid.
DNA constitutes the molecules inside
cells that carry genetic information and
pass it from one generation to the next.
DNA is made up of 4 bases (adenine, guanine, cytosine, and thymine) which are
each bonded to a sugar (deoxyribose) and a phosphate to make nucleotides. These
are repeated in various sequences along the molecule. Complementary bases pair
to form a double helix structure. The sequence of nucleotides makes a gene which
is used to make proteins.
