1
Q

what are the two stages of the cell cycle?

A

interphase and mitotic (M) phase

2
Q

How to remember mitotic phase

A

I prefer mince and tatties cold

Interphase, prophase,metaphase,anaphase, telophase, cytokinesis

3
Q

what does interphase involve?

A

G1-growth and DNA synthesis
S phase-DNA is replicated
G2-further growth phase and ATP is built up

4
Q

what is cytokinesis?

A

the cytoplasm is separated into two daughter cells

5
Q

what is the prophase?

A

DNA condenses into chromosomes, consisting of two sister chromatids
membrane breaks down: spindle fibres extend from the MTOC by polymerisation
attach to chromosomes in the centromere region

6
Q

what is the metaphase?

A

chromosomes are aligned at the metaphase plate (equator)

7
Q

what is the anaphase?

A

spindle microtubules shorten by depolymerisation
sister chromatids are separated
chromosomes are pulled to opposite poles

8
Q

what is telophase?

A

chromosomes decondense and membranes are formed around them
