Final answer:
Recombination machinery is important for the proper disjunction of chromosomes during meiosis. It facilitates exchange of genetic material, ensures accurate repair of DNA, and promotes separation of homologous chromosomes.
Step-by-step explanation:
The important of the recombination machinery for proper disjunction of chromosomes is supported by the observation that recombination serves to exchange genetic material on homologous chromosomes. During meiosis, homologous chromosome pairs migrate as discrete structures that are independent of other chromosome pairs. Recombination nodules mark the points of later chiasmata and mediate the multistep process of crossover, or genetic recombination, between the non-sister chromatids. These mechanisms ensure accurate repair of damaged DNA and ensure the proper separation of homologous chromosomes during meiosis I.
