Dinoflagellates possess condensed chromosomes even in interphase, their nucleus is called

Astral body are formed of

The small disc shaped like structures occur in the centromere are called as

Human ------------- do not divide after birth.

In animal cells, during G2 phase

Division of nucleus without being followed by cytokinesis results into

Plant mitosis is generally controlled by

Arrange the order of events taking place in anaphase II stage of meiosis:
a. Metaphase plate spilts
b. Each chromosome moves away from equatorial plane
c. Centromeres split and chromatids separate.
d. Chromatids move to opposite poles

In diploid cells,each homologous chromosome consists of

The resting phase is otherwise called as
