WebAug 8, 2024 · There are 2 parts to the cell cycle: interphase and mitosis/meiosis. Interphase can be further subdivided into growth 1 (G1), synthesis (S), and growth 2 (G2). During the G phases, the cell grows by producing various proteins, and during the S phase, the DNA is replicated so that each chromosome includes 2 identical sister chromatids. WebJun 8, 2024 · When a cell undergoes mitosis, the chromosomes condense even further. DNA replicates in the S phase of interphase. After replication, the chromosomes are composed of two linked sister chromatids. When fully compact, the pairs of identically-packed chromosomes are bound to each other by cohesin proteins.
