B. Synthesis

Question

Match the following Column-I with Column-II:

Column-I
A. Synapsis aligns homologous chromosomes
B. Synthesis of RNA and protein
C. Action of enzyme recombinase
D. Centromeres do not separate, but chromosomes move towards opposite poles

Column-II
(i) Pachytene
(ii) Zygotene
(iii) G2-phase
(iv) Anaphase I

Accepted Answer

Based on the provided text: 
1. Synapsis (A): Occurs during the Zygotene (ii) stage of Prophase I, where chromosomes start pairing together .
2. Synthesis of RNA and protein (B): Occurs during the G2 phase (iii) of interphase, where proteins are synthesised in preparation for mitosis .
3. Action of enzyme recombinase (C): Crossing over is an enzyme-mediated process (involving recombinase) that occurs during the Pachytene (i) stage  (though 'Pachytene' was missing from the specific input snippet, it is the standard match for this event in the source text).
4. Centromeres do not separate (D): During Anaphase I (iv), homologous chromosomes separate, but sister chromatids remain associated at their centromeres .
