|
|
Term
|
Definition
results in new cells wth genetic material that is identical to that of the original cell
(the usual method of cell division, characterized typically by the resolving of the chromatin of the nucleus into a threadlike form, which condenses into chromosomes, each of which separates longitudinally into two parts, one part of each chromosome being retained in each of two new cells resulting from the original cell.) |

| second phase of mitosis. chromosomes are easier to identify using a microscope than during other phases |
|
|
Term
|
Definition
