the prophase 1 of meiosis plays important role in r-DNA formation.justify.

Prophase I is the longest phase of meiosis. It consists of pachytene as one of the phase in which the recombination nodules appear at the sites where crossing over has to take place between non-sister chromatids of homologous chromosomes. Crossing over helps in the exchange of genetic material between two homologous chromosomes with the help of enzyme recombinase. Thus, results in formation of r DNA or recombinant homologous chromosomes.
