Heteroduplex - Wikipedia
A heteroduplex is a double-stranded molecule of nucleic acid originated through the genetic recombination of single complementary strands derived from different sources, such as from different homologous chromosomes or even from different organisms.
8.6: Holliday Model for General Recombination - Biology LibreTexts
2023年6月20日 · In 1964, Robin Holliday proposed a model that accounted for heteroduplex formation and gene conversion during recombination. Although it has been supplanted by the double-strand break model (at least for recombination in yeast and higher organisms), it is a useful place to start.
8.7: Double-strand-break model for Recombination
2023年6月20日 · In the single strand invasion model, each DNA duplex has heteroduplex material covering the region from the initial site of exchange to the migrating branch, i.e. the heteroduplexes are symmetric.
Mitotic Recombination: Why? When? How? Where? - PLOS
2009年3月13日 · A heteroduplex is a region of DNA composed of strands that are derived from two different chromosomes. Polymorphisms between the two chromosomes will result in mismatches, and repair of these mismatches can result in gene conversion.
Recombination: Mechanisms, Pathways, and Applications
2017年5月16日 · Haploid cells of opposite mating type (a and α) fuse to form a diploid yeast cell (only one chromosome is shown, for simplicity). The diploid cell in this example is heterozygous for three genetic markers (A, B, and C) because the haploid cells carried different alleles at …
Heteroduplex And Homoduplex DNA: Image Details - NCI Visuals …
Heteroduplex And Homoduplex DNA Description: DNA duplexes; drawing shows double-stranded homoduplex DNA with the normal binding of wild-type DNA sequences (labeled A-T and G-C).
Heteroduplex analysis - Wikipedia
Heteroduplex analysis (HDA) is a method in biochemistry used to detect point mutations in DNA (Deoxyribonucleic acid) since 1992. [1] Heteroduplexes are dsDNA molecules that have one or more mismatched pairs, on the other hand homoduplexes are dsDNA which are perfectly paired.

In nucleic acid: General recombination. …identical will be a “heteroduplex”—that is, a molecule in which mismatched bases will be present at some positions in the helix.
Heteroduplex analysis (HA) is a technique in which heteroduplex structures can be directly detected on polyacrylamide gels because they migrate slower than their corresponding homoduplexes.

2018年1月1日 · A DNA mismatch is defined as a non-Watson-Crick nucleotide base pair (also called heteroduplex) in dsDNA, where Watson-Crick base pairs (i.e., homoduplexes) are guanine:cytosine (G:C) and adenine:thymine (A:T). The structures of several heteroduplexes are shown in Fig. 1.
