Which phase of the cell cycle is DNA replicated?

When the cell has reached an appropriate size and is in a supportive environment for DNA replication, it will exit either G1 or G0 and enter the next phase of interphase called S phase. S phase, or synthesis, is the phase of the cell cycle when DNA packaged into chromosomes is replicated.

Similarly, you may ask, which cell cycle is DNA replicated?

During Mitosis, DNA is replicated during the S phase (Synthesis phase) of Interphase. Interphase is basically the daily life cycle of the cell. Cells spend most of their life in Interphase before Mitosis occurs (M phase).

Which stage of mitosis is DNA replicated?

Interphase is divided in to 3 phases such as G-phase, S-phase and G1-phase . Mitotic phase,here mitosis and meiosis occurs and it contains prophase,metaphase,Anaphase and telophase. DNA synthesis happens in S-phase i.e. synthesis phase of interphase where cell division preparation happens.

How is DNA replicated in the S phase?

Interphase begins with G1 (G stands for gap) phase. During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids (see figure below).
