Question 2

List the stages of interphase

Answer 2

G1, S, G2 Stages

Question 3

Explain what happens in the G1 stage.

Answer 3

• Create proteins and organelles needed for DNA synthesis

Question 4

Explain what happens in the S stage.

Answer 4

• Synthesis (replication) of its DNA

Question 5

Explain what happens in the G2 stage.

Answer 5

• Preparing/rearranging the cell for mitosis

Question 6

List the main stages in the M-Phase.

Answer 6

• Mitosis

Question 7

List (in order) the stages of Mitosis.

Answer 7

• Prophase
• Metaphase
• Anaphase
• Telophase

Question 8

Explain the process of Prophase

Answer 8

2 copies of DNA wind up tightly into chromosomes.

Question 9

Explain the process of Metaphase

Answer 9

Chromosomes line up along the equator of the cell.

Question 10

Explain the process of Anaphase

Answer 10

Chromosomes are pulled apart.

Question 11

Explain the process of telophase

Answer 11

• Chromosomes move to opposite ends (poles) of the cell.
• Nucellar membrane forms in the centre of the cell.

Question 12

Explain the process of Cytokinesis

Answer 12

The psychical separation of the cytoplasm of a cell.

Answer 13

2 daughter cells
