Q. At what stage of the cell cycle are histone proteins synthesized in a eukaryotic cell ?
A) During entire prophase
B) During telophase
C) During S-phase
D) During G2 stage of prophase
Explanation
[Solution from source] Histones are made in the S phase, at the same time as DNA replication, so the newly copied DNA can be packed into nucleosomes straight away. Prophase and telophase are stages of mitosis, and G2 is not part of prophase. Answer (3).
