NEETBiologyCell Cycle and Cell DivisionMCQ+4 / −1
The enzyme recombinase is required at which stage of meiosis?
  1. A
    Pachytene
  2. B
    Zygotene
  3. C
    Diplotene
  4. D
    Diakinesis
View written solutionFree

Correct answer: A

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