Select the correct option:
 
  I   II
(a) Synapsis aligns homologous chromosomes (i) Anaphase – II
(b) Synthesis of RNA and protein (ii) Zygotene
(c) Action of enzyme recombinase (iii) G2 – phase
(d) Centromeres do not separate but chromatids move towards opposite poles (iv) Anaphase – I
    (v) Pachytene

Solution

Synapsis of homologous chromosome - Zygotene.
Synthesis of RNA & protein - G2 phase.
Action of enzyme recombinase - Pachytene.
Centromeres do not separate but chromatid move towards opposite pole - Anaphase-I.

In Anaphase-II, the centromere splits and each half chromosome moves to opposite poles.
