2.6 Cell Division , Diversity & Organisation

Question 1

What is the cell cycle?

Answer 1

In eukaryotes, the cell readies itself for division before mitosis occurs

G1 - the growth phase
cells grow and increase in size, transcription of genes to make RNA, organelles duplicate, biosynthesis

G0 - a resting phase triggered during G1 by a checkpoint chemical
cells may undergo apoptosis (programmed cell death) or differentiation and may or may not remain in this phase for a long time

S1 - DNA replicated

Question 2

What is cellular division?

Answer 2

Cells reproduce by duplicating their contents and then splitting into two daughter cells

Question 3
