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.
The running out of the nuclear energy from the star indicates that the star is about to die and it can die in so many ways. The Supernova explosion is one way that the star might die, triggering the beginning of a new star's life cyce. The Supernova is said to be the greatest explosion that can happen in space.
I believe the answer is chromosome or dna
Your answer is Interphase
G1, S, and G2 make up the process called interphase
