Which of the following combinations of "phase of a cell cycle and its corresponding DNA content" can be considered normal?<br>(i) Diploid cells found in the $G_0$ or $G_1$ phase.<br>(ii) Cells with twice the normal DNA content in the early M phase.<br>(iii) Cells with intermediate amounts of DNA in the S phase.<br>(iv) Cells with twice the normal DNA content in the $G_2$ phase.

Question 23 :
Synthesis phase in the cell cycle is called so, because of the synthesis of more

Question 24 :
When a cell stops growing say due to shortage of nutrients, this will occur in which phase of the cell cycle?

Question 26 :
When the cell has stalled DNA replication, which check point should be predominantly activated ?

Question 28 :
Select the correct option:Which phase occupies the maximum part of cell cycle?
