At what stage of the cell cycle are histone proteins synthesized in a eukaryotic cell?

  1. A
    During entire prophase
  2. B
    During telophase
  3. C
    During S-phase
  4. D
    During G2 stage of prophase

Solution & Step-by-step Explanation

Histone proteins are synthesized during the S-phase of the cell cycle. This is because histones are necessary for the packaging of DNA into chromatin, and the S-phase is when DNA replication occurs. So, the correct answer is option C. Notice that prophase is a stage of mitosis, and histone synthesis is not specific to this stage. Therefore, options A and D are incorrect. Option B is also incorrect because telophase is a stage of mitosis that occurs after the S-phase.
