Detailed explanation-1: -In the eukaryotic cell cycle, chromosome duplication occurs during “S phase” (the phase of DNA synthesis) and chromosome segregation occurs during “M phase” (the mitosis phase).
Detailed explanation-2: -Solution : interphase in a cell cycle has three stages ‘-G (1), S‘ and ‘G (2)‘ M-phase is not a part of interphase.
Detailed explanation-3: -Cell duplication is preceded by a process called mitosis, in which the replicated chromosomes are separated into two new nuclei. Mitosis is the prerequisite for a cell to divide into two identical ones.
Detailed explanation-4: -In most somatic cells, centriole duplication occurs during S phase and is marked by the formation of procentrioles at the proximal end of each parental centriole.
