WebWhat would be the most obvious outcome of repeated cell cycles consisting of S phase and M phase only? The cells produced would get smaller and smaller. Which of the following events does NOT usually occur during interphase? The nuclear envelope breaks down. Which of the following statements about the cell cycle is FALSE? WebS phase is the period of wholesale DNA synthesis during which the cell replicates its genetic content; a normal diploid somatic cell with a 2N complement of DNA at the beginning of S phase acquires a 4N complement of DNA at its end. (Recall that N = 1 copy of each chromosome per cell [haploid]; 2N = 2 copies [diploid].)
