Question

$G_1$ stage of interphase of cell cycle shows

• A. Active synthesis of DNA
• B. Active synthesis of RNA
• C. Active synthesis of protein
• D. Both B and C

Answer 1

The correct option is D Both B and C

Interphase is composed of $G_1$ phase (cell growth), followed by S phase (DNA synthesis), followed by $G_2$ phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells. G1 phase together with the S phase and $G_2$ phase comprise the long growth period of the cell cycle cell division called interphase that takes place before cell division in mitosis (M phase). During $G_1$ phase, the cell grows in size and synthesizes mRNA and protein that are required for DNA synthesis.
So, the correct option is D.
