Enzyme involved in crossing over

Question

cdquestions Admin · Accepted Answer

The correct answer is: Option 2: Recombinase Explanation: Recombinase enzymes play a crucial role in the process of crossing over during meiosis . These enzymes facilitate the recombination of genetic material between homologous chromosomes by enabling the exchange of DNA segments. Recombinase is involved in creating Holliday junctions , which are key intermediates in genetic recombination. The other options are incorrect because: Ligase (Option 1) is involved in joining DNA fragments but is not specifically involved in crossing over. Polymerase (Option 3) synthesizes DNA but does not directly participate in the crossing-over process. Endonuclease (Option 4) makes cuts in DNA, but it does not directly regulate the exchange of genetic material during crossing over. Thus, recombinase is the enzyme involved in the crossing-over process.
