3 0

Answer:

the S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. in this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

in S phase, the cell synthesizes a complete copy of the DNA in its nucleus. it also duplicates a microtubule-organizing structure called the centrosome. the centrosomes help separate DNA during M phase.
