heteroduplex


Also found in: Dictionary, Encyclopedia, Wikipedia.

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

[-do̅o̅′pleks]
Etymology: Gk, heteros + L, duoplicare, to double
a DNA molecule in which the two strands are derived from different individuals, with the result that some base pairs may not be complementary.

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.
