C)homotriplex
D)heterotriplex

Question

Quizplus · Accepted Answer

Heteroduplex regions on the DNA during recombination are necessary for gene conversion to occur. Heteroduplex regions are formed when two homologous chromosomes exchange genetic material, resulting in a pairing of non-identical DNA strands. This pairing creates a joint molecule that contains both parental and recombinant DNA sequences, allowing for gene conversion to take place. Homoduplex and homotriplex regions do not involve exchange of genetic material between homologous chromosomes and therefore cannot lead to gene conversion. Heterotriplex regions may occur in some cases, but they are not essential for gene conversion to occur.
