mitosis vs meiosis
Definitions
noun
- cell division in which the nucleus divides into nuclei containing the same number of chromosomes
Examples
Gross changes in chromosome morphology occur at each mitosis.
It is generally assumed that DNA chains are randomly segregated to daughter cells during mitosis.
It is undisputable that mitosis and cytokinesis, although tightly coupled in most cells, can often be uncoupled, suggesting that these two processes are actually independent, even though they usually cooperate to bring about cell division.
Definitions
noun
- (genetics) cell division that produces reproductive cells in sexually reproducing organisms; the nucleus divides into four nuclei each containing half the chromosome number (leading to gametes in animals and spores in plants)
- understatement for rhetorical effect (especially when expressing an affirmative by negating its contrary)
Examples
Barot A, Kleckner N (2008) Yeast Pch2 promotes domainal axis organization, timely recombination progression, and arrest of defective recombinosomes during meiosis.
This can happen either occasionally during cell wounding or regularly during cytokinesis and meiosis.
Sutton worked with grasshopper chromosomes, and it was in this paper that he showed that chromosomes occur in distinct pairs, which segregate at meiosis.
