Question

Select the correct statement about G${}_1$ phase:

• A. Cell is metabolically inactive
• B. DNA in the cell does not replicate
• C. It is not a phase of synthesis of macromolecules
• D. Cell stops growing

Answer 1

The correct option is B DNA in the cell does not replicate

Interphase has a long duration and during this phase, the cell prepares to divide by undergoing cell growth and DNA replication. Interphase is divided into $G_1$ , S and $G_2$ phases.
During $G_1$ phase, cells are metabolically active and cellular contents are synthesized and thus there is overall cell growth. It grows in size by synthesizing macromolecules like RNA and proteins.
During S phase, the total content of DNA gets doubled.
During the $G_2$ phase, proteins needed for cell division are synthesized.
