Detailed explanation-1: -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.
Detailed explanation-2: -S phase is the period during which DNA replication occurs.
Detailed explanation-3: -Once all of the DNA is replicated and the twin chromatids form, the cell transitions from the S phase to G2. The G2 phase features rapid protein synthesis and cell growth. During this time, the cell builds up its supply of a protein complex called the maturation promotion factor, or MPF.
Detailed explanation-4: -So, S stands for DNA synthesis. After the DNA is copied and there’s a complete extra set of all the genetic material, the cell moves into the G2 stage, where it organizes and condenses the genetic material, or starts to condense the genetic material, and prepares to divide. The next stage is M. M stands for mitosis.
Detailed explanation-5: -During S phase, genomic DNA is replicated and packaged into chromatin. The identical copies of each chromosome are known as sister chromatids, and they are tightly associated together through G2 phase and early mitosis.
