Q. The enzyme recombinase is required at which stage of meiosis?

AIPMTAIPMT 2014Cell Cycle and Cell Division

Solution:

Pachytene is characterized by the appearance of recombination nodules, the sites at which crossing over occurs between non-sister chromat ds of the homologous chromosomes. Nodules contain multienzyme complex called recombinase. Recombinase is made of endonuclease, exonuclease, unwindase, R-protein, etc.
