The Cell Cycle- Interphase

Question 1

What are the phase order?

Answer 1

M phase
G0 phase
G1 phase
S phase
G2 phase

Question 2

What M phase?

Answer 2

When cells stops growing.

Question 3

What is G0 phase? (A,D)

Answer 3

Resting phase happens before G1.
Differentiation (speilisation)
apoptosis (programmed cell death-> creating fingers)

Question 4

What is G1phase? (c,t,o,e)

Answer 4

Cells increase in size
Transcription -> RNA
Organelles duplicate
Making enzymes for DNA synthesis.

Question 5

What happens in S? (D, h&i, q)

Answer 5

-DNA replicates chromosomes consist of 2 sister chromatids contented by centromere

-Housekeeping genes are duplicated first inactive genes last.
-Happens quickly so DNA is not exposed to mutations

Question 6

What happened in G2 phase? (G, p&s)

Answer 6

-Ensures cell is ready for mitosis (cell growth).
-Proteins condense chromosomes and form spindle fibres
-Organisms divide
