cell cycle question

I'm trying to arrange each phase of cell cycle in order of duration from the shortest to the longest. I'm not sure whether this is something that's gonna show up on real DAT, but I confronted this kind of problem on cliffs and kaplan once.

I know each phase of mitosis (prophase, metaphase, anaphase, telophase) is shorter than cytokinesis and interphase. So my guess is (from the shortest to the longest)

metaphase< anaphase < prophase = telophase < cytokinesis < G2 of interphase < S < G1

I have no idea whether they are correct or not, but from the cliffs, it says the metaphase is the shortest and kaplan says G1 is the longest b/c it takes lots of time making proteins and other stuffs.

Does anyone know the correct sequence?
Thanks in advance 🙂

i always thought anaphase was faster than metaphase because when they pull the chromosomes apart by the spindle apparatus is it immediate as opposed to metaphase which takes a bit more time for everything to line up.

Metaphase can occupy a large portion of the total time of mitosis because chromosome alignment at the center of the cell on the metaphase plate acts as a checkpoint for progression into the next phase, anaphase. Cells can arrest in metaphase for days until the chromosomes are properly aligned and the cell enters anaphase.


The entire duration of anaphase is relatively short, usually only lasting a few minutes.

u forgot G0.thats the longest.

Thanks guys for your input!
It makes sense about the metaphase and anaphase (I guess it's another mistake on Kaplan!) and I completely forgot about the G0 phase. So,

anaphase < metaphase < prophase = telophase < cytokinesis < G2 < S < G1 < G0..

does it look alright? I'm still not sure about the interphase tho..
