Mitosis: Splitting Up is Complicated - Crash Course Biology #12

Hank describes mitosis and cytokinesis - the series of processes our cells go through to divide into two identical copies"

Maybe a little bit advanced for GCSE but you know, every little helps :)

Some of the terms might not be needed for GCSE biology but this video is useful nevertheless. It might be useful to pause the video every so often and make some notes as the presenter can speak rapidly at times.

Report

  • In mitosis a cell splits to create 2 identical copies, for growth and repair.
  • The daughter cells are diploid (2 sets of chromosomes). The chromosomes line up, get pulled apart and the cytoplasm closes around them. The chromosomes have to replace themselves first.
  • Mitosis produces new cells for:
    Growth
    Repairing damaged body parts
    Asexual reproduction

    Asexual reproduction:
    No fertilisation
    When bacteria split in two
    Produces genetically identical offspring
