Transcription and replication occur during the S phase of the cell cycle. During this phase, DNA is replicated to ensure that each daughter cell receives an identical set of genetic information. Transcription, the process of synthesizing RNA from a DNA template, can also occur throughout the cell cycle but is particularly active during the S phase as cells prepare for division.
Interphase
DNA replication occurs during interphase.
Transcription occurs multiple times during each round of the cell cycle, particularly during the interphase stages (G1, S, and G2). In these phases, genes are transcribed as needed for cell growth, DNA replication, and preparation for mitosis. During mitosis (M phase), transcription is largely halted as the cell focuses on chromosome segregation. Overall, the frequency of transcription events varies depending on the specific needs of the cell at different points in the cycle.
Chromosomal replication occurs during the S phase of the cell cycle, which is part of interphase. During this phase, the DNA in a cell is replicated to ensure that each daughter cell will receive a complete set of chromosomes.
During the G1 phase of the cell cycle, the cell grows and carries out its normal functions. This is followed by the S phase, during which DNA synthesis and replication occur. Finally, the G2 phase takes place, where the cell prepares for mitosis.

DNA replication occurs during the S phase of the cell cycle, which is before mitosis begins.

DNA replication occurs during interphase.
Chromosome replication occurs during the S phase of the cell cycle. This is when DNA is synthesized to ensure that each daughter cell receives an identical copy of the genetic material during cell division.
The semiconservative replication of DNA occurs in the S phase or interphase of cell cycle. Mutation too occurs during this phase, whereas growth takes place in G phase.
Genetic mutations occur during the S phase of the cell cycle (during interphase before mitosis or meiosis begins). This is when DNA is replicated, so any error would cause a mutation in the genetic code. Chromosomal nondisjunction is the failure of replicated chromosomes to separate, which causes extra or missing chromosomes in the daughter cells. This mutation can occur during meiosis I or II and during mitosis.
