Question
In the cells of some organisms, repeated cytokinesis can sometimes occur without the accompanying mitotic phase. This results in _____.
cells with more than one nucleus
cells lacking nuclei
cells that are unusually small
destruction of chromosomes
cell cycles lacking an S phase
cells that are unusually small with most lacking a nucleus
a.cells with more than one nucleus
b.cells lacking nuclei
c.cells that are unusually small
d.destruction of chromosomes
e.cell cycles lacking an S phase
f.cells that are unusually small with most lacking a nucleus
Explanation / Answer
Destruction of chromosomes is the result of a cell which undergoes repeated cytokinesis without accompanying mitotic phase.It is because
The central problem for a cell undergoing cytokinesis is to ensure that it occurs at the right time and in the right place. Cytokinesis must not occur too early in M-phase, or it will disrupt the path of the separating chromosomes. It must also occur at the right place to separate the two segregating sets of chromosomes properly so that each daughter cell receives a complete set.
