The average menstrual cycle is 28 days from Day 1 to Day 1 of your period. However, anywhere from 25 to 31 days between periods is considered a normal menstrual cycle. The best thing to do when you suspect that you're experiencing abnormal bleeding or menstrual cycles is to consult with your health care provider.
During interphase, the cell is preparing to divide and is actively synthesizing the required components. Originally and inaccurately referred to as the resting stage, the interphase is actually a period in which a considerable degree of activity is taking place on the sub-cellular and molecular level.
The correct answer is anaphase ll. During this phase the kinetichore fibers, attach to the centromeres of the chromosomes, while they are lined up on the metaphase plate. These special fibers then split apart the chromosome and bring them to opposite parts of the cell. The cell then splits apart as a reslt of cytokinesis.
