Summarise Interphase
DNA replicates, leading to 2 chromatids joined at a centromere.
number of organelles and volume of cytoplasm increases
Summarise Mitosis
nucleus divides to produce two nuclei with identical copies of DNA produced by parent cell
Summarise Cytokinesis
cytoplasm and cell membrane divide to form 2 new genetically identical daughter cells
Why do cells undergo mitosis?
Growth, Replacing cells and asexual reproduction
How do prokaryotic cells replicate?
Binary fission
Describe stages of binary fission
Replication of circular DNA and plasmids. Division of cytoplasm to produce two daughter cells. There is a single copy of circular DNA however variable number of copies of plasmids.
How do viruses replicate?
They do not undergo cell division as they are non-living.
Attachment proteins attach to complementary receptors on host cell. Viral nucleic acid is injected into host cell.
Infected Host cell replicates virus particles.
