The process of replication occurs during the S phase of the cell cycle. WebJul 7, 2024 · Replication begins when helicase enzymes unzip various locations along the chromosome, separating the two complementary strands of DNA. What occurs in G2 phase? DNA replication occurs during this S (synthesis) phase. Gap 2 (G2): During the gap between DNA synthesis and mitosis, the cell will continue to grow and produce new … WebDuring mitosis the sister chromatids separate and go to opposite ends of the dividing cell. Mitosis ends with 2 identical cells, each with 2N chromosomes and 2X DNA content. All eukaryotic cells replicate via mitosis, except germline cells that undergo meiosis (see below) to produce gametes (eggs and sperm). eastern oregon bare land for sale
