The diagram shows the cell cycle. During which phase do chromosomes condense and become visible?

Step-by-step solution

Interphase, therefore, consists of G 1 , S, and G 2 . During G 1 , cells make the RNA, enzymes, and other proteins needed for growth. At the end of G 1 , 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 G 2 phases of interphase. Prophase is marked by the initiation of condensation of chromosomal material. T
