THE CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What happens during Gap 2?
A
During Gap 2, protein and organelle synthesis occurs to prepare for cell division.
B
During Gap 2, the cell grows and synthesizes proteins needed for synthesis to occur.
C
During Gap 2, the cell changes its size in order for cytokinesis to occur.
D
During Gap 2, the replicating of DNA occurs in order for the cell to divide.
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: -So, what happens in G2 of the cell cycle? The second growth phase starts to prepare the cells with newly replicated DNA for entry into the mitosis phase by putting in place the necessary organelles for mitosis.

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: -Gap 2 Phase This last stage is all about prepping the cell for mitosis or meiosis. During G2, the cell has to grow some more and produce any molecules it still needs to divide. This includes assembly of the microtubules, which will make up an important structure called the spindle during mitosis.

Detailed explanation-5: -The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
