WebbProphase is characterized morphologically by profound changes in the cell’s architecture to detach from the substrate and become round in shape as well as condensation of chromatin into chromosomes. WebbMeiosis is preceded by an interphase consisting of G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase (the “first gap phase”) is focused on cell growth. During the S phase—the second phase of interphase—the cell copies or replicates the DNA of the chromosomes.
