Answer 2

It is the between G1 and S phase (G1 – S)

• If the cell cross the R point then the cell is destine of the complete cell cycle

Question 3

Which protein helps in Major R check point ?

Answer 3

By G1 cyclin + CdC2 kinase

Question 4

What is the Minor check point ?

Answer 4

It is the between G2 and M phase (G2 – M)

Question 5

Which protein helps in Minor check point ?

Answer 5
