Interphase
|
|
|
Growth phase
|
|
|
Mitotic phase

|
Synthesis Phase

Explanation:
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: -S phase : The replication phase is known as the S phase. DNA replication consumes the majority of the cell’s resources. All 46 chromosomes are duplicated in human cells.
Detailed explanation-3: -DNA synthesis occurs during interphase. Complete step-by-step answer: The cell cycle of animal cells has two main stages: the Interphase and M phase. Interphase is the preparatory phase that is further divided into Gap1 (G1) phase, Synthesis (S) phase, and Gap2 (G2) phase.
