NEET Biology question
Study the following columns and match each item in Column-I with the most appropriate item in Column-II (one item in Column-II is not used).
List-I: (A) Initiation of spindle fibres (B) Synthesis of RNA and protein (C) Action of endonuclease (D) Movement of chromatids towards opposite poles
List-II: (1) Anaphase-I (2) Zygotene (3) G₁-phase (4) Pachytene (5) Anaphase-II
Solution
B – G1-phase (3): RNA and protein synthesis is characteristic of the growth phase G1. C – Pachytene (4): the endonuclease/recombinase activity that initiates crossing over acts during pachytene. D – Anaphase-II (5): sister chromatids (as opposed to whole homologous chromosomes) separate and move to opposite poles
