CELL DIVISION

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: -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.

Detailed explanation-4: -Mitotic Phase Its organelles are also duplicated. This happens in the interphase. Then, when the cell divides (mitotic phase), it occurs in two major steps, called mitosis and cytokinesis, both of which are described in greater detail in the concept Mitotic Phase: Mitosis and Cytokinesis.
