Definition of amitotic in English:



  • Relating to or denoting the division of a cell nucleus without mitosis.

    • ‘Tetrahymena divide by binary fission during vegetative growth, and the micronucleus and macronucleus are propagated by mitotic and amitotic division, respectively.’
    • ‘Changes in the structure and ultrastructure of protoplasts during regeneration of the cell wall, mitotic cell division and amitotic nuclear fragmentation.’
    • ‘As a result, the normal complement of DNA in the micronucleus is 4C during the amitotic division of the macronucleus and cytokinesis.’
    • ‘They show some rare mitotic figures; signs of amitotic division could never be found.’
    • ‘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.’
