During gamete formation, the enzyme recombinase participates during
Options
- AMetaphase I.
- BAnaphase II.
- CProphase I.
- DProphase II.
Correct answer
C. Prophase I.
Step-by-step solution
Gamete formation occurs by meiosis, and enzyme recombinase helps in the process of recombination or crossing over which occurs during pachytene of Prophase I of meiosis. This stage is characterized by the appearance of recombination nodules, the sites at which crossing over occurs between nonsister chromatids of the homologous chromosomes.
