Unformatted text preview: subphase of interphase draw the cell cycle, what is meant by the term “cycle” In the cell cycle? What is happening at the s phase and the m phase? M phase = nuclear division (mitosis) and cytoplasmic division (cytokinesis) S phase = DNA synthesis, chromosomes are replicated (aka DNA effectively doubled) in the cell cycle, at which stages do two chromatids make up one chromosome? S? does the cell cycle refer to mitosis as well as meiosis? it is possible that an alternate mechanism for generating germ cells could have evolved. Consider meiosis in a germ cell precursor (a cell that is diploid but will go on to make gametes). If the s phase were skipped, which meiotic division (meiosis I or meiosis II) would no longer be required?...
