Question

Assertion: `G_(1)` phase is the interval between mitosis and initiation of DNA replication.
Reason: The cell is metabolically inactive druing `G_(1)` phase.
A. If both assertion and reason are true and reason is the correct explantion of assertion
B. If both assertion and reason are true but reason is not the correct explnantion of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Answer 1

Correct Answer - C
`G_(1)` phase is also known as first growth phase or post mitotic gap phase. It is the phase between end of mitotic phase of previous cell and initiation of S-phase of next mitotic phase. During `G_(1)` phase the cell is metabolically active and continously grows. In this phase different types of RNA (mRNA,fRNA and rRNA) and proteins are synthesised.
