Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which pair includes a phase of the cell cycle and a cellular process that occurs during that phase?
A
G1 phase, DNA replication
B
G2 phase, preparation for mitosis
C
S phase, cell division
D
M phase, cell growth
Explanation: 

Detailed explanation-1: -Which pair includes a phase of the cell cycle and a cellular process that occurs during that phase? mitosis and cytokinesis.

Detailed explanation-2: -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-3: -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-4: -The G2-phase checkpoint, also known as G2/M-phase checkpoint, has the function of preventing cells with damaged DNA, lasting from the G1 and S phases or generated in G2, from undergoing mitosis.

Detailed explanation-5: -G2 is the shortest phase of interphase. It is when organelles and proteins necessary for cell division are produced. The cell requires a bunch of proteins and other stuff to separate the chromosomes and divide the cell in half. All of these materials are produced during G2.
