Which process occurs during Interphase?

• A. Chromosome condensation occurs
• B. DNA, RNA, and protein synthesis takes place
• C. Cytokinesis occurs
• D. Spindle formation occurs

Answer: (B)

Interphase is the cell’s growth and preparation period between divisions, encompassing G1, S, and G2. During this time the genome is replicated in S phase, so DNA synthesis occurs. At the same time, the cell continues transcription and translation to support growth and prep for mitosis, meaning RNA and protein synthesis take place. In contrast, chromosome condensation and spindle formation are events of mitosis, and cytokinesis happens after mitosis. Therefore, DNA, RNA, and protein synthesis occurring during interphase is the best fit.
