0 the type of cell division in which one cell divides into two cells that are exactly the same, each with the same number of chromosomes as the original cell:
Our skin cells are continually replaced by mitosis.
1 the type of cell division in which one cell divides into two cells exactly the same, each with the same number of chromosomes (= cell structures) as the original cell
This nucleus gives rise at the first embryonic mitosis to 20 bivalents which coexist with 20 somatic chromosomes originating from the female pronucleus.
Cells undergoing mitosis appeared spherical, covered with blebs and anchored to the substrate by retraction fibres.
In this context, it is important to point out that the first divisions after karyogamy tend to deviate from the common pattern of mitosis.
Cycling cytoplasmic factors that promote mitosis in the cultured 2-cell mouse embryo.
These fragments appeared to be generated through the destruction of nuclei upon entry to mitosis.
In the present study we have found that the sister blastomeres of tetraploid embryos reconstructed by fusion can also enter mitosis asynchronously.
We conclude, therefore, that the replication-sensitive checkpoints that operate during mitosis are absent or inactive during meiosis.
We cannot exclude the possibility that the spindle assembly checkpoint acts during the first mitosis.
