mitosis

Question 1

what cells does mitosis affect?

Answer 1

Somatic cells

Question 2

what happens when parent cells are copied?

Answer 2

they make two genetically identical daughter cells

Question 3

whats the result of mitosis?

Answer 3

genetically identical daughter cells

Question 4

what are the three reasons cell replication occurs?

Answer 4

1. growth
   2.repair
2. procreation

Question 5

what are the 4 stages of mitosis?

Answer 5

1. prophase
2. metaphase
3. anaphase
4. telophase
   (PMAT)

Question 6

what happens during interphase (before mitosis)

Answer 6

DNA in the cell doubles from 46 to 92

Question 7

what happens during prophase

Answer 7

. chromosomes become visible
. centrioles move to the poles of the cell, and start to create spindle fibres
(p for prohase, when moving to opposite poles)

Question 8

what happens during metaphase

Answer 8

. spindle fibres connect to chromatids
. chromatids move to the middle of the cell
. nuclear membrane disappears
(m for metaphase, when chromatids move to the middle)

Question 9

what happens during anaphase

Answer 9

. chromosomes divide, separating sister chromatids
. spindle fibres shorten, pull chromosomes away from the middle of cell
(a for anaphase, when chromsomes are pulled away)

Question 10

what happens during telophase

Answer 10

. new nuclei form around chromosomes making two new nuclei
. spindle fibres disappear

Question 11

what happens during cytokinesis (after mitosis)

Answer 11

the cell separates into two daughter cells
