Benchmark Review

DNA is replicated during ______ of the cell cycle.

• Gap 1

• Synthesis (S phase)

• Gap 2

• Gap 0

What is cytokinesis?

• This is when two cells merge together to make one giant cell.
• The stage where chromosomes migrate to the opposite ends of the cell. 
• The stage of the cell cycle where the rest of the cell divides after mitosis is complete.
• The stage in which DNA condenses into chromosomes.

What occurs during G1?

• Checkpoint after S phase
• Chromosomes line up at the equator.
• The cell grows and develops.
• Spindle fibers separate chromosomes to opposite poles of the cell.
