At what stage of the cell cycle are histone proteins synthesized in a eukaryotic cell?
Correct answer: B. During S-phase
- A. During G2 stage of prophase
- B. During S-phase
- C. During the entire prophase
- D. During telophase
Explanation
During the S phase or synthetic phase, the replication of DNA takes place. For replication of DNA, histone proteins are required so they are also synthesized during this phase. It takes about 30% 50% of the total cell cycle. Prophase and telophase are stages involved in mitosis or meiosis. During the G2 phase, the division of centrioles, mitochondria and chloroplasts occurs.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
