Question

$G_2$ phase occurs between
A) $G_1$ and S
B) M and S
C) S and M
D) G1 and M

Answer 1

Cell division is a process where one cell divides to form two or more identical cells. Based on the type of cell that divides, cell division is off mitosis and meiosis. Mitosis occurs in somatic cells where a parent cell divides to form two identical daughter cells and meiosis occurs in germ cells where a parent cell divides to form four cells with reduced ploidy.

Complete answer:
The cell division has two major phases that are Interphase and Mitotic phase (in case of mitosis) and Meiotic phase (in case of meiosis). Interphase is the preparatory phase where The cell synthesises all the necessary proteins and mRNA which is required for DNA replication and other cellular processes.

Interphase has three major phases $G_1$ , S and$G_2$. The $G_1$(Gap 1) phase is the first phase where mRNA and protein synthesis occurs. S phase ( Synthesis phase) in which DNA replication occurs, this phase is highly conserved among the organisms. $G_2$ phase (Gap 2) is the third phase which is followed by mitosis. In this phase there is rapid growth of proteins which is necessary for completion of the cell cycle.

Hence, the correct answer is Option ‘C’.

Note: Chromatin remains untangled in interphase and is seen as a ball of wool also called a spiremea spireme stage. Cell enters mitosis after it bypass check points such as spindle assembly.
