Question

What is the function of enzyme recombinase during meiosis

• A. Formation of synaptonemal complex.
• B. Crossing over between nonsister chromatids.
• C. Condensation of chromosomes.
• D. Alignment of bivalent chromosomes O equatorial plate.

Answer 1

The correct option is A Formation of synaptonemal complex.

The synaptonemal complex (SC) is a protein structure that forms between homologous chromosomes (two pairs of sister chromatids) during meiosis and is thought to mediate chromosome pairing, synapsis, and recombination. Crossing over is an enzymatic process occurring during the pachytene stage of prophase-1. The enzyme involved in this process is called recombinase which acids in the recombination of genes between homologous chromosomes.

So, the correct answer is 'Formation of synaptonemal complex.'.
