DNA is replicated during ______ of the cell cycle.

• Gap 1

• Synthesis (S phase)

• Gap 2

• Gap 0

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. 

During most of interphase, DNA is found in a relaxed form called

• chromosome

• centromere

• centriole

• chromatin

During mitosis, DNA is found in the condensed form called a

• chromosome

• centromere

• centriole

• chromatin
