DNA synthesis does not exist and what you are probably looking for cell reproduction or cell mitosis. In cell mitosis there are 6 phases which is interphase when the cell makes the centrioles and begins preparing for the duplication of DNA. In prophase DNA is copied from the nucleus, metaphase aligns the DNA for the split, anaphase separates the DNA and centrioles, and in telophase the cell splits into two separate DNA and centriole developing into 2 new cells.
The DNA is synthesized during the S-phase of the cell's Interphase (G1, S, G2)... That is why it is called the "S" phase-- standing for the word "synthesis".
Interphase
No. DNA synthesis occurs in the S phase. Cells in the G0 phase are not preparing for cell division.
DNA synthesis is represented by the S phase of the cell cycle.
S-phase of interphase
The stage in the cell cycle when DNA is copied is the S phase of the interphase. It refers to the resting phase between successive mitotic divisions of a cell.
Within the Cell cycle, Dna synthesis occurs during the S [synthesis] phase.
Interphase (synthesis)
Synthesis phase or "S phase" occurs during the interphase of a cell cycle between the G1 and G2 stages. During synthesis phase, DNA molecules "unzip" and each old strand attracts free nucleotides forming complementary new strands, leaving two strands of DNA identical to the original strand of DNA.
S-phase (synthesis phase) is the part of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase.
The phase in which DNA copies itself is called DNA replication. This process occurs during the S phase of the cell cycle and involves the synthesis of a new DNA strand using the existing DNA strand as a template. DNA replication is essential for cell division and passing on genetic information to daughter cells.
