an alteration in the genetic material of a cell that is transmitted to the cell’s offspring. Mutation may be spontaneous (the result of accidents in the replication of genetic material) or induced by external factors (e.g., electromagnetic radiation and certain chemicals).

Mutations take place in the genes, which are found in the long, chainlike molecules of deoxyribonucleic acid (DNA). The backbone of the DNA chain is composed of alternating sugar and phosphate groups. Protruding from each sugar group is oneof four nitrogenous bases: adenine (A), guanine(G), thymine (T), or cytosine (C). Structurally, each DNA molecule consists of two entwined chains, linked together by bonds between the bases of one chain and those of the other. An A is always bonded to a T, and every G is paired with a C; the result is that the sequence of bases in the two strands is complementary.
