Interphase

Question 1

Within multicellular organisms, not all cells retain the ability to divide

Eukaryotic cells that do retain the ability to divide show a cell cycle

Mitosis is part of a precisely controlled process known as the cell cycle

Question 2

What is the cell cycle

Answer 2

The cell cycle is the regulated sequence of events that occurs between one cell division and the next

Question 3

three stage of the cell cycle

Answer 3

interphase

nuclear division (mitosis)

cell division (cytokinesis)

Question 4

The length of the cell cycle is very variable depending on

Answer 4

environmental conditions, the cell type and the organism

Question 5

The movement from one phase to another is triggered by chemical signals called

Answer 5

cyclins

Question 6

During Interphase the cell

Answer 6

increases in mass and size and carries out its normal cellular functions (eg. synthesising proteins and replicating its DNA ready for mitosis)

Question 7

Interphase consists of three phases

Answer 7

G1 phase
S phase
G2 phase
