Detailed explanation-1: -Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division. If all conditions are ideal, the cell is now ready to move into the first phase of mitosis.
Detailed explanation-2: -Duplication of chromosomes occurs during the interphase. During interphase, the cell grows and the nuclear DNA is duplicated. The cell duplicates its chromosomes and ensures its systems are ready for cell division.
Detailed explanation-3: -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-4: -S phase (DNA Synthesis)-Each of the 46 chromosomes are duplicated by the cell.
