THE CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What occurs after cytokinesis is completed?
A
The cell organizes its microtubules
B
The cell begins to replicate its DNA
C
The cell enters G1
D
The cell enters G2
Explanation: 

Detailed explanation-1: -After the completion of the cytokinesis, each of the daughter cells starts another cell cycle by entering into the interphase.

Detailed explanation-2: -The G1 phase is a period in the cell cycle during interphase, after cytokinesis (process whereby a single cell is divided into two daughter cells) and before the S phase. For many cells, this phase is the major period of cell growth during its lifespan.

Detailed explanation-3: -After cytokinesis, the organelles reassemble in each daughter cell. Some of these, such as mitochondria and chloroplasts, replicate from existing bodies.

Detailed explanation-4: -Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents.

Detailed explanation-5: -Cytokinesis begins in anaphase and ends in telophase, reaching completion as the next interphase begins.
