Prophase. a) It is the first stage of mitosis where the chromosomes become shorter and thicker and have clear visibility. b) Chromosomes are identical to paired chromatids. c) Sister chromatids link to each other at a little region called the centromere. d) Centrioles begin moving apart …
WebMitosis involves a nuclear division that produces two genetically identical daughter cells through the stages of prophase, prometaphase, metaphase, anaphase, and telophase. Mitosis is a reasonably short stage of the cell cycle, preceded by the long interphase. In preparation for the division, the cell synthesizes mRNA and proteins during gap 1 ... 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. Interphase & mitosis.
Web29 apr. 2024 · The cell cycle contains two distinct phases: interphase (also called I phase) and mitosis (also called M phase). During interphase, the cell prepares to divide by undergoing three subphases known as G 1 phase, S phase and G 2 phase. Some cells remain in interphase for days or even years; some cells never leave interphase.
