Prophase: Prophase starts immediately after G 2 stage of interphase. Chromosomes look like thin thread and uncoiled in the early prophase (Fig. 3.2B), but become shortened, coiled and more distinct during mid-prophase (Fig 3.2C). In the late prophase, chromosomes appear more conspicuous, short and thick and longitudinally double (Fig. … iron and wine call it dreaming lyrics

WebMitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase. Interphase is often included in discussions of mitosis, but interphase is technically not part of mitosis, but rather encompasses stages G1, S, and G2 of the cell cycle. The cell is engaged ...
