cell cycle division/mitosis

Question 1

reasons for cell divis

Answer 1

growth repair maintenance

Question 2

mitosis

Answer 2

part of cell cycle when dna in nucleus divides

Question 3

4 stages of mitosis

Answer 3

PMAT
prophase
metaphase
anaphase
telophase

Question 4

chromatin

Answer 4

threads of dna which contain hereditary info, forms chromosomes

Question 5

chromosomes

Answer 5

structures in nucleus carry dna thats passed onto offspring

Question 6

sis chromatids

Answer 6

pairs of identical dna joined by centromere

Question 7

daughter chromosomes

Answer 7

when sis chromosomes separate

Question 8

prophase

Answer 8

chromatin condenses
nucleus disappears
chromosomes appear (two sis chromatids)

Question 9

metaphase

Answer 9

spindle fibre complete
chromosomes attached at centromere
chromosomes lined up at equator

Question 10

anaphase

Answer 10

chromosomes separate = daughter chromosomes pulled to opp ends by spindle fibres shortening

Question 11

telophase

Answer 11

cytokinesis begins
cell plate growing to perimeter of cell
nuclear membrane reforming, spindle disappeared

Question 12

cytokinesis

Answer 12

cytoplasm divides completing cell division

Question 13

interphase

Answer 13

beginning of cell cycle, functions normally, dna copied for cell division
