Chapter 9 Cell Cycles
- Cytokinesis is the division of the cytoplasm
- Chromosome segregation – the equal distribution of daughter chromosomes to each of
the two cells that result from cell division
- The longest phase in mitosis is the interphase where cell grows and duplicates.
- In interphase there is G ph1se, S phase then G phase 2
- During prophase chromosomes condense into rod like structures and the nucleolus
disappears, meaning that RNA synthesis disappears.
- During prometaphase the nuclear envelope breaks down and spindles form, and
chromosomes attach to spindles.
- During metaphase the chromosomes are ligned up at the spindle midpoint.
- During anaphase sister chromatids separate and move to opposite spindle poles.
- During telophase the spindle disassembles and chromosomes decondense and
nucleolus and envelope reappear.
- Animal cells use furrowing and plants use cell plate formation in cytokinesis.
- Animal cells use centrosomes to create spindle
