The correct Answer is:
To solve the matching question, we need to correctly pair the items from Column 1 with the appropriate items from Column 2 based on our knowledge of cell cycle and cell division. ### Step-by-Step Solution: 1. **Identify the first option: "Synapsis aligns homologous chromosomes."** - **Explanation:** Synapsis is the process where homologous chromosomes pair up during prophase I of meiosis. This occurs specifically during the zygotene stage of prophase I. - **Match:** (a) → (iii) "Zygotene" 2. **Identify the second option: "Synthesis of RNA and protein."** - **Explanation:** The synthesis of RNA and proteins occurs during the G2 phase of the cell cycle, which is a preparatory phase before mitosis. - **Match:** (b) → (ii) "G2 phase" 3. **Identify the third option: "Action of enzyme recombinase."** - **Explanation:** The enzyme recombinase is involved in genetic recombination, which occurs during the pachytene stage of prophase I in meiosis. - **Match:** (c) → (v) "Pachytene" 4. **Identify the fourth option: "Centromeres do not separate but chromatids move towards opposite poles."** - **Explanation:** This statement describes the process that occurs during anaphase I of meiosis, where homologous chromosomes are pulled apart, but the sister chromatids remain attached at the centromere. - **Match:** (d) → (iv) "Anaphase I" ### Final Matches: - (a) → (iii) "Zygotene" - (b) → (ii) "G2 phase" - (c) → (v) "Pachytene" - (d) → (iv) "Anaphase I"
