cell division

Question 1

The cell cycle has three phases what are they

Answer 1

interphase, mitosis(nuclear division), cell division (cytokinesis)

Question 2

what happens during interphase

Answer 2

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

Question 3

what are the 3 phases of interphase

Answer 3

G1 phase, S-phase, G2 phase

Question 4

what happens during G1

Answer 4

Cell grows and receives a signal to divide,

Question 5

what happens during S-phase

Answer 5

Synthesis of new DNA, DNA replicate in nucleus( 2 identical sister chromatids)

Question 6

what happens during G2 phase

Answer 6

Further cell growth
Error checking of newly synthesised DNA

Question 7

what is cyclins

Answer 7

Further cell growth
Error checking of newly synthesised DNA

Question 8

what occurs after interphrase

Answer 8

nuclear division- mitosis- referred to as the m phase, cell growth stops

Question 9

what happens after mitosis

Answer 9

cytokenisis- cell split into 2 identical individual cells

Question 10

what is mitosis

Answer 10

Mitosis is the process of nuclear division by which two genetically identical daughter nuclei are produced that are also genetically identical to the parent nucleus

Question 11

what is the importance of mitosis

Answer 11

repairs damaged cells and growth

Question 12

how many stages are there

Answer 12

4- Prophase, metaphase, anaphase, telophase
