[3 Marks]

• A. Statements P, Q, and R
• B. Statements P, R, and S
• C. Statements R, T, and U
• D. Statements R, Q, and T

Answer 1

The correct option is C Statements R, T, and U

The G1 phase is often referred to as the growth phase because a cell grows in this phase. This is the longest phase of the cell cycle. During this phase, the cell synthesizes various RNA and proteins that are later required for DNA replication and cell division. The next phase of G1 is the S phase that constitutes the synthesis of DNA. So, the G1 phase marks the interval between the mitotic or M phase and S phase.
