CELL DIVISION AND CANCEROUS CELLS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
After G2, the cell has ____
A
duplicated its DNA
B
duplicated its organelles
C
divided
D
created two gametes
Explanation: 

Detailed explanation-1: -The organelles necessary for the cell division (in M phase) are also synthesized in the S phase. The microtubules that will be used to mobilize the chromosomes in M phase are assembled at G2.

Detailed explanation-2: -Understanding Stages Of The Cell Cycle : Example Question #1 G1 and G2 are both growth phases, during which cellular organelles are replicated and the cell grows in size.

Detailed explanation-3: -G2 phase (Gap 2)-The Cell “double checks” the duplicated chromosomes for error, making any needed repair.

Detailed explanation-4: -It follows the successful completion of S phase, during which the cell’s DNA is replicated. G2 phase ends with the onset of prophase, the first phase of mitosis in which the cell’s chromatin condenses into chromosomes.
