Question

During the synthesis phase of the cell cycle, more of ______.

Options

• RNA is synthesised.

• RNA and proteins are synthesised.

• DNA is synthesised.

• Glucose is synthesised.

Answer 1

During the synthesis phase of the cell cycle, more of DNA is synthesised.

Explanation:

The synthesis phase, or S phase, is a vital stage of interphase where the cell replicates its genetic material. During this time, a complete and precise copy of the cell’s DNA is created to ensure that both future daughter cells receive an identical genome. Cellular growth, along with major RNA and protein synthesis, happens instead during the surrounding gap phases (G₁ and G₂).
