ANSWERS GUARANTEED PASS
⫸ What is the method of cell division used to replace/repair cells?
Answer: Mitosis.
⫸ What happens during interphase? Answer: The cell grows, copies its
DNA, and prepares for cell division.
⫸ Name the steps of mitosis. Answer: Prophase
Metaphase
Anaphase
Telophase
⫸ What happens during prophase? Answer: Chromosomes condense
and centrioles move to opposite poles, forming spindle fibres.
⫸ What happens during metaphase? Answer: Chromosomes line up at
equator of cell. Spindle fibres attach to centromeres.
, ⫸ What happens during anaphase? Answer: Spindle fibres contract,
sister chromatids pulled to opposite sides of cell. Centromere dives.
⫸ What happens during telophase? Answer: Chromosomes uncoil.
Nuclear envelope reforms. Spindle fibres and centrioles break down.
⫸ What happens during cytokinesis? Answer: Cytoplasm divides, two
new cells formed.
⫸ What does the parent cell produce in mitosis? Answer: 2 genetically
identical daughter cells.
⫸ Why is mitosis important? Answer: Produces cells for growth/repair
and asexual reproduction.
⫸ How do prokaryotic cells replicate? Answer: Binary fission.
⫸ What is the process of binary fission. Answer: DNA and plasmids
replicate.
Cytoplasm extends and each copy of DNA (and variable number of
plasmids) move to opposite poles.
Cytoplasm divides.
2 daughter cells produced.
