A student records three events in the cell cycle.
P: chromatids move towards opposite poles
Q: DNA is replicated
R: chromosomes line up at the equator
Which is the correct order of these events?
P→Q→RP \rightarrow Q \rightarrow RP→Q→R
Q→P→RQ \rightarrow P \rightarrow RQ→P→R
R→Q→PR \rightarrow Q \rightarrow PR→Q→P
Q→R→PQ \rightarrow R \rightarrow PQ→R→P
