MCQ
Between mitosis, a cell is said to be in the:
  • ✓
    Resting stage
  • B
    Sleeping stage
  • C
    Active stage
  • D
    None of the above

Answer

Correct option: A.
Resting stage
Interphase is a complex of changes that occur in a newly formed cell before it is able to divide.
Interphase is also called preparatory phase, inter$-$mitosis or energy phase.
Previously, it was known as a resting phase.
It is characterized by three substages, $G1​ ($growth phase $1$ or gap $1), S ($ synthesis $)$ and $G2​ ($ growth phase $2$ or gap $2).$ It is an active part of a cell's life cycle and in $G1$​ many metabolic reactions occur including protein synthesis.
During $S$ phase, $\text{DNA}$ replication occurs and $G2$​ is marked by synthesis of $\text{RNA}$ and proteins.
