Which phase does a cell typically enter after cytokinesis?

G1 S G2 M

Correct Answer:

Explanation:

After cytokinesis, the cell finishes dividing its cytoplasm and re-enters interphase, starting with the first stage called G1. In G1 the cell grows, carries out normal functions, and checks that conditions are favorable before copying its DNA. Only after G1 does it move into S phase for DNA replication, then G2 to prep for another division. Mitosis, which includes prophase through cytokinesis, has just concluded with cytokinesis, so the next phase is G1.
