CHROMOSOMES AND CELL DIVISIONS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
This is the part of the cell cycle that the cell is preparing for cell division
A
Interphase
B
Mitotic phase (M)
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA.

Detailed explanation-2: -The interphase is the period when the cell is in a non-dividing state and this can be in different stages: the first gap (G1) between the last mitosis and the S phase (phase of DNA synthesis) and the second gap (G2) between the completion of the S phase and the next mitosis (M).

Detailed explanation-3: -During interphase, the genetic material of the cell is duplicated. New cells have to have genetic material, and so a cell cannot divide unless it has a second set of DNA to pass on to the new cell.
