the cell cycle is the series of events that take place in a cell that causes it to divide into two daughter cells
it is essential to maintain a suitable number of cells
cell division refers to the process in which
eukaryotic cell cycle
mitosis produces two identical daughter cells that are genetically identical to the parent cell (diploid)
meiosis produces two different daughter cells gametes, for sexual reproduction (haploid)
| state | phase | abbreviation | description |
|---|---|---|---|
| resting | gap 0 | the cell is not in the cell cycle and is not dividing | |
| interphase | gap 1 | ensures that everything is ready for DNA synthesis | |
| interphase | synthesis | DNA replication | |
| interphase | gap 2 | growth and preparation for mitosis | |
| cell division | mitosis or meiosis | cell division happens |
prokaryotic cell cycle
all prokaryotic cells replicate using binary fission
here are 2 types of prokaryotic cells, bacteria and archaea.
prokaryotic cells do not contain a nucleus or membrane bound organelles
the cell wall of most bacteria is made of peptidoglycan
they have one circular chromosome of DNA which floats in the cytoplasm, called the nucleoid, as well as small circular pieces of DNA called plasmids
