Meiosis: A reproductive cell divides twice. Cytokinesis happens at the end of telophase I and telophase II. 2. Daughter Cell Number Mitosis: Two daughter cells are produced.

WebbThere are four stages of mitosis: prophase, metaphase, anaphase and telophase. 1) Prophase. Chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres. 2) Metaphase. Chromosomes line up along the metaphase plate (centre of the cell). 3) Anaphase. Webb26 mars 2016 · Dummies has always stood for taking on complex concepts and making them easy to understand.

Meiosis I Before entering meiosis I, a cell must first go through interphase. As in mitosis, the cell grows during G _1 1 phase, copies all of its chromosomes during S phase, and prepares for division during G _2 2 phase.
Webb10 mars 2024 · In biology, mitosis refers to the cellular process where a single cell divides resulting in two identical cells. By identical, it means that both cells have the same number of chromosomes and genetic content. The mitosis steps include preprophase (in plant cells), prophase, prometaphase, metaphase, anaphase, and telophase. Webb30 maj 2024 · The steps of meiosis include 2 stages: meiosis I and meiosis II. Meiosis 1 definition: the first stage in the meiotic division or the reduction division of the meiosis. This is because the number of chromosomes is reduced to half in this stage resulting in the formation of the haploid number of chromosomes.
