During gamete formation, the enzyme recombinase participates during

Options

A. Anaphase-II
B. Prophase-I
C. Prophase_II
D. Metaphase-I

Answer

To solve the question regarding the participation of the enzyme recombinase during gamete formation, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context of Gamete Formation**:
- Gamete formation occurs through a specialized type of cell division called meiosis, which reduces the chromosome number by half.

2. **Identify the Stages of Meiosis**:
- Meiosis consists of two main stages: Meiosis I and Meiosis II. Each of these stages has its own phases: prophase, metaphase, anaphase, and telophase.

3. **Focus on Prophase I**:
- Prophase I is particularly important because it is subdivided into five substages: leptotene, zygotene, pachytene, diplotene, and diakinesis.

4. **Recognize the Role of Recombination**:
- Recombination, which is the exchange of genetic material between homologous chromosomes, occurs during the pachytene substage of prophase I. This process is facilitated by the enzyme recombinase.

5. **Evaluate the Options**:
- The question provides four options: anaphase II, prophase I, prophase II, and metaphase I.
- Since recombinase is involved in the process of crossing over, which occurs during the pachytene stage of prophase I, the correct answer must be prophase I.

6. **Conclude the Answer**:
- Therefore, the enzyme recombinase participates during **prophase I** of meiosis.

### Final Answer:
The enzyme recombinase participates during **prophase I** of gamete formation.
