CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In which stage of the cell cycle is protein and organelle synthesis. The cell prepares for mitosis.
A
G1
B
G2
C
S
D
Cytokinesis
Explanation: 

Detailed explanation-1: -During the second gap phase, or G 2start subscript, 2, end subscript phase, the cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis.

Detailed explanation-2: -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-3: -Protein Synthesis during G2 Phase Is Required for Normal Mitotic Progression. So far, we have shown that inhibition of either Wee1/Myt1 or p38 can overcome a cycloheximide-induced arrest and allow G2 phase cells to progress into mitosis in the absence of protein synthesis.

Detailed explanation-4: -During the cell cycle, RNA and protein synthesis takes place during the G1 and G2 phases. The cell cycle is an ordered set of events, culminating in cell growth and division into two daughter cells.

Detailed explanation-5: -The G2 phase continues growth of the cell and prepares the cell for mitosis (M phase) by producing all of the enzymes that the cell will need in order to divide. Color the G2 phase light blue. After the G2 phase of interphase, the cell is ready to start dividing.
