mitosis

Question 1

G1

Answer 1

Increase size, makes more proteins +organelles

Question 2

S

Answer 2

Chromosomes replicated

Question 3

G2

Answer 3

Organelles + molecules needed for cell division made. Duplicated DNA checked for errors

Question 4

Prophase

Answer 4

Uncoiled chromosomes condense into chromosomes
Centrioles separate to opposite sides of the nucleus
Spindle fibers form from centrioles
Nuclear membrane breaks down

Question 5

Metaphase

Answer 5

Chromosomes lineup in middle (metaphase plate)
Spindle fibers attach to centromere of each chromosome

Question 6

Anaphase

Answer 6

Sister chromatids separate into individual chromosomes
Separate into 2 groups on opposite sides of cell

Question 7

Telophase

Answer 7

Chromosomes at opposite ends of cell and lose shape (decondense to form chromatin)
Nuclear membrane forms around cluster of chromosomes
Cell pinches inward between cell’s poles

Question 8

Cytokinesis

Answer 8

By end of cytokinesis cell is completely divided
Each cell has two identical chromosomes
