Mitosis

Why do cells move through the cell cycle?

• reproduction

• growth

• repair damaged cells

• all of the above are reasons

90% of the cell cycle is spent in

• prophase

• interphase

• metaphase

• anaphase

What occurs during G1 of interphase?

• cell growth

• DNA replication

• preparation for mitosis

• chromosome alignment

What occurs during the S phase of interphase?

• cell growth

• DNA replication

• sister chromatids are separated

• preparation for mitosis

During the cell cycle

• 2 genetically different cells are produced

• 4 genetically identical cells are produced

• 2 genetically identical cells are produced

• no cells are produced

Diploid cells have ____ set(s) of chromosomes; haploid cells have _____ set(s) of chromosomes.

• 1; 1

• 1; 2

• 2; 1

• 0; 2

If the haploid # of a cell is 16, the diploid # would be

• 8

• 16

• 32

• 64

Mitosis refers to

• growth of a cell.

• division of the cell.

• replication of chromosomes.

• the division of the nucleus.

Uncontrolled / unregulated cell growth

• cell cycle

• cancer

• interphase

• metaphase

sister chromatids separate

• interphase

• prophase

• anaphase

• telophase
