"WebIn the S phase, the DNA of the chromosomes is replicated. Finally, in the G 2 phase, the cell undergoes the final preparations for meiosis. During DNA duplication of the S phase, each chromosome becomes composed of two identical copies (called sister chromatids) that are held together at the centromere until they are pulled apart during meiosis II.
