Biology 180: Mitosis

Question 1

Mitosis

Answer 1

makes cells genetically identical to parent cells

for growth replacement, asexual reproduction

typically in non-reproductive (somatic) tissues

Question 2

Process of Mitosis

Answer 2

1. Interphase
2. Prophase
3. Metaphase
4. Anaphase
5. Telephase
6. Cytokinesis

Question 3

Interphase for Mitosis

Answer 3

when the chromatin/chromosomes replicate

cell spends most of its time in interphase before going into mitosis

Question 4

Prophase

Answer 4

• chromosomes condense
  chromatin: unwound genetic
  information/long strands
  chromosome: condensed genetic
  information/compact
• nuclear envelope begins to disintegrate
• spindle apparatus begins to form

Question 5

Metaphase

Answer 5

chromosomes move to the center and line up single-file along the equator of the cell

Question 6

Anaphase

Answer 6

2 sister chromatids separate and move towards opposite poles

Question 7

Telophase

Answer 7

• chromosomes start to de-condense
• nuclear envelope begins to form
• spindle fibers break down and disappear

** 1 diploid cell -> 2 identical diploid cells

Question 8

Cytokinesis for Mitosis

Answer 8

separate from the mitosis

division of the cytoplasm
typically occurs after mitosis
mechanism varies according to cell type
