Question

# During cell growth, DNA synthesis takes place in

A
G2 phase
B
M pahse
C
S phase
D
G1 phase

Solution

## The correct option is A S phaseInterphase is the period between two subsequent M phases and consists of three phases: $$G_1$$, S phase (the period of DNA replication) and $$G_2$$ phase. The $$G_1$$ phase is the gap between M phase and S phase and is marked by synthesis of RNA and protein (excluding histones) and duplication of all cell content except DNA.S phase of DNA replication and cell division is followed by $$G_2$$ phase during which cell double-checks the duplicated DNA content.Therefore, the correct answer is option C.Biology
