Which of the following statements is correct?

Solution:

Let's analyze each statement:

(1) Cell cycle is a highly regulated and genetically controlled process, involving various checkpoints and regulatory proteins (like cyclins and CDKs). Therefore, this statement is incorrect.

(2) DNA replication occurs during the S (synthesis) phase of interphase, which precedes Meiosis I. Interkinesis is the short resting period between Meiosis I and Meiosis II, during which no DNA replication takes place. Therefore, this statement is incorrect.

(3) Duplication of cell organelles, such as mitochondria and chloroplasts, primarily occurs during the G1 phase and continues through the S and G2 phases to ensure that each daughter cell receives an adequate number of organelles. While the word "only" makes this statement technically imprecise, significant organelle growth and preparation for division, including the completion of duplication, do occur in the G2 phase. Compared to the other options, which are fundamentally incorrect, this statement is considered the most appropriate answer.

(4) RNA synthesis (transcription) is an active process throughout the interphase (G1, S, and G2 phases) as the cell needs to synthesize various proteins and enzymes for growth and preparation for cell division. Therefore, this statement is incorrect.

Based on the analysis, option (3) is the most plausible correct answer among the given choices, despite the slight inaccuracy of the word "only".
