Unit 5

Question 1

interphase

2n-diploid

Answer 1

• centrosome & chromosome

- DNA is copied

Question 2

prophase

2n - diploid

Answer 2

• the chromosomes pair up

Question 3

metaphase

2n - diploid

Answer 3

• chromosomes line up at equator

- & there’s a mitotic spindle

Question 4

anaphase

2n - diploid

Answer 4

• sister chromatids pulled apart

Question 5

telophase & cytokinesis

2n - diploid

Answer 5

cell punches in the middle & two identical daughter cells are formed

Question 6

interphase

n-haploid 2n - diploid

Answer 6

• centrosome & chromosomes are

- DNA is copied

Question 7

prophase 1

n - haploid 2n- diploid

Answer 7

chromosomes pair up

recombination occurs

Question 8

metaphase 1

n - haploid 2n - diploid

Answer 8

• chromosomes line up at equator

- msiotic spindle

Question 9

anaphase 1

n- haploid 2n - diploid

Answer 9

chromosomes are pulled apart

Question 10

telophase 1 and cytokinesis

n - haploid 2n - diploid

Answer 10

cell pinches in the middle

Question 11

prophase 2

n-haploid 2n - diploid

Answer 11

two daughter cells

Question 12

metaphase 2

n- haploid 2n - diploid

Answer 12

chromosomes line up at equator

Question 13

anaphase 2

n-haploid 2n diploid

Answer 13

• sister chromatids pulled apart

Question 14

telophase 2 and cytokinesis

n-haploid 2n diploid

Answer 14

• cell pinches in the middle

- four granddaughter cells

Question 15

what is passed onto daughter cells?

Answer 15

Organelles, cell membrane, cytoplasm, enzymes, and the exact copy of genetic material which equals DNA

Question 16

g1 phase

Answer 16

• cell doing its everyday job

- cell grows

Question 17

G0 phase

Answer 17

• the cell is an extending g1 phase

- the cell is neither dividing nor preparing to divide

Question 18

S phase synthesis (4)

Answer 18

• synthesis phase during interphase
• dividing cell replicates DNA
• MUST separate DNA copies correctly to 2 daughter cells
• each daughter cell get a completely identical copy

Question 19

G2 phase

Answer 19

• prepares for cell division
• cells grow (more)
• produces organelles, proteins, and membranes

Question 20

What are g1, S, and g2 collectively called?

Answer 20

interphase

Question 21

G0 phase is also known as

Answer 21

• a non-dividing working state

Question 22

g1/ S checkpoint

Answer 22

can DNA synthesis begin?

Question 23

g2 / M checkpoint

Answer 23

• has DNA synthesis been completed correctly

- commitment to mitosis

Question 24

spindle checkpoint

Answer 24

• are all chromosomes attached to a spindle

- can sister chromatids separate correctly?
