Chapter 10

Question 1

G1

Answer 1

Cell is biochemically active and gathers materials and energy for mitosis

Question 2

S

Answer 2

DNA is copied

• sister chromatids are joined at the centromere
• centrosomes produce mitotic spindles

Question 3

G2

Answer 3

Organelles are duplicated
Energy is replenished
Cytoskeleton breaks down

Question 4

Prophase

Answer 4

Nuclear membrane dissolves and chromosomes are made

Question 5

Metaphase

Answer 5

Duplicated chromosomes align at the middle of the cell

Question 6

Anaphase

Answer 6

Sister chromatids are pulled apart

Question 7

Telophase

Answer 7

2 nuclear memebranes are created

Question 8

Cytokenisis

Answer 8

Splitting of cytoplasm
Nuclear memebrane is back
Chromosomes are made into chromatin
Nucleolus is apparent again

Question 9

Mitosis/karyokenisis

Answer 9

Prophase
Metaphase
Anaphase
Telophase

Question 10

Prophase

Answer 10

Chromosomes condense
Spindle fibers emerge from the centrosome
Nuclear envelope breaks down
Nucleolus dissapears
Kinetochores form
Centrosomes move to opposite poles
Organelles move toward the edges of the cell
Mitotic spindles attach to kinetochores

Question 11

Metaphase

Answer 11

Mitotic spindles is fully developed
Centrosomes are on opposite poles of the cell
Chromosomes are lined up on the metaphase plate
Each sister chromatid is attached to a spindle fiber originating from opposite poles

Question 12

Where are the checkpoints in the cell cycle

Answer 12

End of G1
G2 to mitosis
Metaphase
