Question

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

• A. During telophase
• B. During S-phase
• C. During G-2 stage of prophase
• D. During entire prophase

Answer 1

The correct option is B During S-phase

Histone is a basic protein( consisting of Arginine and Lysine). These proteins are basically involved in the formation of an Octamer which then with linker DNA forms nucleosome around which core DNA is wounded. These histone proteins are synthesised in the eukaryotic cell in S-phase.

So, the correct answer is 'During S-phase'.

So the correct option is B.
