MCQ
During gamete formation, the enzyme recombinase participates during
- Ametaphase $I$
- Banaphase $II$
- ✓prophase $I$
- Dprophase $II.$
✓
Answer
Correct option: C.
prophase $I$
c
(c) : 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 nonsister chromatids of the homologous chromosomes. Crossing over is the exchange of genetic material between two homologous chromosomes. Crossing over is also an enzymemediated process and the enzyme involved is called recombinase.
