Question
If there are 20 centromeres in a cell at anaphase, how many chromosomes are there in each daughter cell following cytokinesis?Group of answer choices10204030
Solution
The answer is 20.
Here's the step-by-step explanation:
-
Centromeres are part of a chromosome, and each chromosome has one centromere.
-
Anaphase is a stage in cell division where the chromosomes separate. At this stage, each chromosome splits at the centromere, creating two sister chromatids.
-
Each sister chromatid has its own centromere, so if there are 20 centromeres at anaphase, that means there are 20 sister chromatids.
-
Cytokinesis is the final stage in cell division where the cell splits into two daughter cells. Each daughter cell receives an equal number of chromosomes.
-
Therefore, if there were 20 sister chromatids (and thus 20 centromeres) at anaphase, there would be 20 chromosomes in each daughter cell following cytokinesis.
