heteroduplex[‚hed·ə·rō′dü‚pleks] (genetics) A double-stranded deoxyribonucleic molecule comprising strands from different individuals. (cell and molecular biology) A double-stranded molecule of deoxyribonucleic acid in which the two strands show noncomplementary sections. heteroduplex
het·er·o·du·plex (het'ĕr-ō-dū'pleks), 1. A DNA molecule, the two constitutive strands of which derive from distinct sources and hence are likely to be somewhat mismatched. 2. A DNA-RNA hybrid. [hetero- + L. duplex, two-fold] het·er·o·du·plex (het'ĕr-ō-dū'pleks) 1. A DNA molecule, the two constitutive strands of which derive from distinct sources and hence are likely to be somewhat mismatched. 2. A DNA-RNA hybrid. [hetero- + L. duplex, two-fold]heteroduplex a DUPLEX DNA in which the two strands do not show COMPLEMENTARY BASE PAIRING throughout, but instead contain one or more MISMATCHES OF BASES. A heteroduplex may be formed during RECOMBINATION, for example. Compare HOMODUPLEX. |
