Vedclass · Answer

(B) During the $pachytene$ stage of $prophase-I$ in meiosis,the phenomenon of crossing over occurs.Crossing over is the exchange of genetic material between non-sister chromatids of homologous chromosomes.This process is mediated and catalyzed by an enzyme complex known as $recombinase$.$Recombinase$ facilitates the breaking and rejoining of $DNA$ strands,ensuring genetic recombination.

In meiosis,crossing over and exchange of genetic material between homologous chromosomes are catalyzed by the enzyme.
