Definition of amitotic in English:

amitotic

adjectiveˌamʌɪˈtɒtɪkˌeɪmʌɪˈtɒtɪkˌamī-

Biology

Relating to or denoting the division of a cell nucleus without mitosis.
〔生〕（细胞核分裂）和无丝分裂有关的；无丝分裂的
Example sentencesExamples
- Fortunately, the amitotic division and high telomerase activity in the large macronucleus allowed Paramecium to be transformed by microinjection of DNA fragments and a method for cloning genes by complementation was developed.
- Tetrahymena divide by binary fission during vegetative growth, and the micronucleus and macronucleus are propagated by mitotic and amitotic division, respectively.
- As a result, the normal complement of DNA in the micronucleus is 4C during the amitotic division of the macronucleus and cytokinesis.
- Changes in the structure and ultrastructure of protoplasts during regeneration of the cell wall, mitotic cell division and amitotic nuclear fragmentation.
- They show some rare mitotic figures; signs of amitotic division could never be found.

Derivatives

amitosis

noun

Biology

Not surprisingly, macronuclei divide by amitosis (except within the class Karyorelictea, in which macronuclear division does not occur).
Example sentencesExamples
- Besides amitosis, cold-pretreatment also induced some abnormal mitotic behavior leading to the formation of micronuclei.
- Because mitotic figures do not occur in adult liver, the binucleate cells are usually assumed to be the result of amitosis, which implies splitting of the nucleus by constriction without the formation of a visible spindle and distinguishable chromosomes.
- Two new micronuclei have formed in what would soon become daughter cells, the macronucleus has undergone amitosis, and Cytokinesis is progressing as the cleavage furrow becomes defined.
- If a deleterious mutation occurs, the chromosome carrying that mutation can be lost following unequal assortment during amitosis of the macronucleus.

amitotically

adverb

Biology

The ‘peanut shell’ stages represent MACs dividing amitotically.
Example sentencesExamples
- The MAC divides amitotically, resulting in a random distribution of chromosome copies.
- In contrast, the somatic macronucleus is polyploid, divides amitotically, and is actively transcribed.
- In contrast, the macronucleus serves as the somatic nucleus, divides amitotically, contains multiple copies of most genes, and is transcriptionally active.
