Explain why the S phase is important in the cell cycle.

• It is when the cell grows

• It is when DNA is replicated

• It is when the cell divides

• It is when the cell rests

Describe the role of spindle fibers during mitosis.

• They help in the replication of DNA

• They attach to chromosomes and help separate them

• They form the cell membrane

• They dissolve the nuclear envelope

What happens during the G2 phase of the cell cycle?

• The cell grows and prepares for mitosis

• The cell divides into two

• The cell rests and does nothing

• The cell undergoes DNA replication
