Question 1

What are the two reasons why cells have to divide?

Answer 1

Repair, Growth

Question 2

Explain what DNA overload means

Answer 2

When the replication system can’t keep up with the demand for DNA.

Question 3

What is the cell cycle?

Answer 3

A series of events where a cell divides and grows.

Question 4

What are the 4 stages of the cell cycle?

Answer 4

G1, S, G2, M phase

Question 5

What are the four stages of mitosis, in order?

Answer 5

Prophase, Metaphase, Anaphase, Telophase

Question 6

Prophase

Answer 6

Chromosomes become visible as paired chromatids and the nuclear envelope disappears.

Question 7

Metaphase

Answer 7

Nucleus dissolves and the cell’s chromosomes condense and move together.

Question 8

Anaphase

Answer 8

Chromosomes move away from each other to opposite sides of the spindle.

Question 9

Telophase

Answer 9

Chromosomes move to opposite ends and create two new nuclei.

Question 10

Interphase

Answer 10

Cell live for 90% of it’s life in this phase.

Question 11

G1

Answer 11

Cells grow during this phase.

Question 12

G0

Answer 12

The cell is neither dividing or preparing to divide.

Question 13

S

Answer 13

DNA is replicated during this time.

Question 14

G2

Answer 14

Cells prepare fir divison.

Question 15
