T Level Health - Mitosis

T Level Health, Core B core science concepts. Template adapted from Canva.com.
B1.6 The function of mitosis in nuclear division within cells:
• mitosis produces 2 daughter nuclei that have the same number of chromosomes as the parent cell
and each other
• mitosis division results in each of the daughter cells having an exact copy of the DNA of the parent cell
B1.7 The purpose of each stage of the cell cycle:
• interphase: stage that always precedes mitosis when DNA is replicated
• stages of mitosis:
o prophase: the stage in which chromosomes become visible and the nuclear envelope
disappears
o metaphase: the stage in which the chromosomes arrange themselves at the centre of the cell
o anaphase: the stage in which each of the 2 threads of a chromosome (chromatid) migrates to
the opposite pole
o telophase: the stage in which the nuclear envelope reforms to produce 2 daughter cells
• cytokinesis: the stage in which division of cytoplasm into 2 daughter cells takes place
