Which statement is true about the events of the cell cycle?
|
|
very little happens during G1 and G2
|
|
|
DNA replicates during prophase
|
|
|
the M phase is usually the longest phase
|
|
|
Cytokinesis is considred a part of the M phase
|
Explanation:
Detailed explanation-1: -Cytokinesis begins in anaphase and ends in telophase, reaching completion as the next interphase begins. The first visible change of cytokinesis in an animal cell is the sudden appearance of a pucker, or cleavage furrow, on the cell surface.
Detailed explanation-2: -During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
Detailed explanation-3: -The next stage is M. M stands for mitosis. This is where the cell actually partitions the two copies of the genetic material into the two daughter cells. After M phase completes, cell division occurs and two cells are left, and the cell cycle can begin again.
