Lily is developing a model of the eukaryotic cell cycle. The model includes mitosis, in which the chromosomes of a cell separate into single-stranded chromatids. Where should Lily show the duplication of the chromatids to prepare for another round of mitosis? A. cytokinesis, which occurs immediately after mitosis
B. either of the two growth phases (G1 or G2) of the cell cycle
C. the S phase of the cell cycle
D. telophase, which is the last phase of mitosis
E. at random phases of the cell cycle
