Does homologous recombination always result in the formation of Heteroduplex DNA? Why or Why not? Introduction: Heteroduplex is a double-stranded DNA molecule of nucleic acids that result from a genetic recombination between single complementary strands of different homologous chromosomes or could be from dissimilar organisms. In meiosis, the crossover happens between two non-sister chromatids that contributes forincrease in different allelic combinations and gametes. The tetrad formation in Prophase - I of meiosis I explains this process that shows the breaking of the sister chromatid strand and formation of Holiday-junction. A source of small RNAs (miRNAs, siRNAs, etc.) is Heteroduplex DNA, that play vital roles in post-transcriptional silencing.
