When 46 chromosomes replicate during interphase, they yield _____ chromatids.

• A. 46
• B. 184
• C. 92
• D. 23

Answer: (C)

Verified step by step guidance

1. Understand that each chromosome consists of one chromatid before replication.
2. During interphase, specifically the S phase, each chromosome replicates to form two sister chromatids.
3. Since the original number of chromosomes is 46, after replication, each chromosome will have 2 chromatids.
4. Calculate the total number of chromatids by multiplying the number of chromosomes by 2: \$46 \times 2$.
5. The result gives the total number of chromatids present after replication during interphase.
