Mitosis

Question 1

Stages of mitosis

Answer 1

Prophase, (prometaphase), metaphase, anaphase, telophase

Question 2

What happens in interphase?

Answer 2

Cells duplicate genetic material and synthesize proteins to prepare for division. Occurs in 3 stages: G1, S, and G2

Question 3

Describe prophase

Answer 3

-Chromosomes condense into 2 sister chromatids
- Centriole split and move to opposite ends of the cell; produce mitotic spindles that extend across cell

Question 4

Metaphase

Answer 4

-Spindle fibers attach at centromere of each chromosome
-Spindle fibers pull chromosomes to middle of cell (metaphase plate)

Question 5

Anaphase

Answer 5

-Chromosomes break apart at centromere
-Spindle fibers pull V-shaped chromatids to opposite sides of cell

Question 6

Telophase

Answer 6

-Chromatids uncoil and become chromosomes again
-Nuclear envelope forms around each set of chromosomes; cell now has 2 nuclei, each w/ complete set of DNA
-Prepare to split cytoplasm by forming cleavage furrow

Question 7

Cytokinesis

Answer 7

Cell completely divides into 2 genetically identical daughter cells
