Section 3-2: Cell Division & Mitosis/Cytokinesis

Question 1

genomic DNA condensation in prokaryotes

Answer 1

1 circular genomic DNA compacted by supercoiling

Question 2

genomic DNA condensation in eukaryotes

Answer 2

linear genomic DNA compacted to a chromosome wraps around histones (proteins)

Question 3

1 chromatid=

Answer 3

1 chromosome

Question 4

2 chromatids=

Answer 4

1 replicated chromosome

Question 5

where does cell division occur?

Answer 5

at meristems (shoot and root)

Question 6

mitosis

Answer 6

division of nucleus

Question 7

cytokinesis

Answer 7

division of cytoplasm

Question 8

interphase

Answer 8

preparing for cell division

Question 9

3 phases and 2 checkpoints of interphase

Answer 9

G1 phase: active cell growth
G1 checkpoint: check for nutrients
S phase: DNA synthesis
G2 phase: DNA repair
G2 checkpoint: check for mutations

Question 10

mitosis acronym and meaning

Answer 10

PMAT
prophase, metaphase, anaphase, telophase

Question 11

prophase

Answer 11

chromosome condensation, wraps around histone
nuclear envelope disappears

Question 12

metaphase

Answer 12

microtubules align chromosomes in middle

Question 13

anaphase

Answer 13

2 sister chromatids move to opposite poles

Question 14

telophase

Answer 14

chromosomes elongate
nuclear envelope formation
cytokinesis starts

Question 15

cytokinesis

Answer 15

phragmoplasts guide vesicles to middle
vesicles fuse together to form cell plate
cell plate attaches to plasma membrane, divides cell

Question 16

which stages of cell cycle contain replicated chromosomes?

Answer 16

after interphase S phase until anaphase

Question 17

which stages of the cell cycle contain highly condensed chromosomes?

Answer 17

prophase, metaphase, and anaphase

Question 18

draw the eukaryotic cell cycle
