Which one of the following stage preceeds mitosis during cell cycle?
Correct answer: C. G2 phase
- A. G1 phase
- B. S phase
- C. G2 phase
- D. M phase
Explanation
The G2 phase directly precedes the M phase in the cell cycle and allows the cell to prepare for mitosis after DNA replication has occurred in S phase. G1 occurs before S phase, whereas M phase is mitosis itself. Students may choose S phase because DNA replication is essential before mitosis, but G2 is the immediate preceding stage.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
