Question

NTA AbhyasNTA Abhyas 2020Cell Cycle and Cell Division

Solution:

Solution
Interphase, therefore, consists of G1, S, and G2. During G1, cells make the RNA, enzymes, and other proteins needed for growth. At the end of G1, the cell becomes committed to dividing or not dividing. The nuclear division follows interphase, referred to as the M phase (M for mitosis). Growth stops temporarily during mitosis. Prophase which is the first stage of karyokinesis of mitosis follows the S and G2 phases of interphase. Prophase is marked by the initiation of condensation of chromosomal material. The chromosomal material becomes untangled during the process of chromatin condensation.
