The Cell Cycle Flashcards
What happens in the interphase?
Everything has to double in capacity, the cell grows to increase numbers of mitochondria and ribosomes. It then duplicates its DNA forming X-shaped pairs of chromatids.
What happens in mitosis?
The nucleus splits, each daughter nucleus having one set of chromatids.
What happens in cytokinesis?
The cytoplasm splits, forming two daughter cells with a nucleus each.
When the cell is not ___, it is in ___.
dividing, the interphase
During cell division, ___ and ___ occur simultaneously (the latter just before the ___).
mitosis, cytokinesis, telophase
How is mitosis used?
- By multicellular organisms to grow in cell number.
- By multicellular organisms to repair damaged cells.
- By some organisms to reproduce by asexual reproduction.
