Problem: Homologous recombination may result in gene conversion when used to fix double-stranded DNA breaks because:A. sister chromatids are always identical.B. the Holliday junction may migrate, resulting in loss of genetic material.C. strand invasion may introduce new genes onto the damaged chromosome.D. homologous chromosomes may carry different alleles of the same gene.

FREE Expert Solution

Homologous recombination is one of the mechanisms that could lead to gene conversion. Gene conversion is basically the process of replacing a gene sequence with the sequence of its homologous chromosome and it would eventually lead to identical sequences for that region.
