Detailed explanation-1: -If there is no S phase, then number of chromosome will decrease by half every generation. This will then create abnormalities within the organism-and these abnormalities can even be fatal-due to non-uniformity of that organism’s chromosome count.
Detailed explanation-2: -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-3: -At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.
Detailed explanation-4: -Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA. So, S stands for DNA synthesis.
