Mitosis: Chromatids to Chromosomes - Answers

[Dooga Blackrazor]

In what phase to chromatids become chromosomes?

That would be Anaphase correct? The kinetochores travel up the spindle fibres after metaphase and separate the double stranded chromsomes. This results in an equal amount of identical chromosomes on each pole of the cell. These chromosomes unwind and lengthen in telophase and Cytokinesis occurs? - or has been occurring and ends.

Also, after Cytokinesis the new cells resemble cells that are "Just beginning Interphase", correct?

Gap 1, Synthesis, Gap 2, Mitosis, Gap 1 would begin and since the new cells resemble Interphase cells, Interphase is just beginning. This also seems consistant with the order.

Are my conclusions correct?, Thanks!

sounds correct to me.

Yes, your conclusions are correct. Chromatids become chromosomes during anaphase when they are separated and pulled to opposite poles of the cell. Cytokinesis then occurs to divide the cell into two daughter cells, which enter the G1 phase of interphase. This is consistent with the order of events in the cell cycle, where mitosis (including anaphase) occurs after the S phase of interphase.
