Q. During gamete formation, the enzyme recombinase participates during

AIPMTAIPMT 2012Cell Cycle and Cell Division

Solution:

During gamete formation, the enzyme recombinase participates during pachytene stage of prophase - I. This stage is characterized by the appearance of recombination nodules, the sites at which crossing over occurs between non-sister chromatids of the homologous chromosomes. Crossing over is the exchange of genetic material between two homologous chromosomes. Crossing over is also an enzyme-mediated process and the enzyme involved is called recombinase.
