| Homoduplex DNA | A double-stranded DNA molecule where both strands are from the same source. Cf. heteroduplex DNA. |
| Deoxyribonucleic acid (DNA) | The molecule that encodes genetic information. DNA is a double-stranded molecule held together by weak bonds between base pairs of nucleotides. The four nucleotides in DNA contain the bases: adenine (A), guanine (G), cytosine (C), and thymine (T). In nature, base pairs form only between A and T and between G and C; thus the base sequence of each single strand can be deduced from that of its partner. |
| Strand | It is customary in genetics to use strand for chromatid. It has therefore been used in that sense in some books, where it has also been used for one double-chain (that is, duplex) DNA molecule. Chain, but not strand, has been used for a single polynucleotide. |
| Heteroduplex analysis | The study of the mobilities of heteroduplex DNA under polyacrilamide gel electrophoresis. The reduced mobility of heteroduplex DNA compared with homoduplex DNA is proportional to the degree of divergence of the sequences. |
