Sister Chromatids: Role and Importance in DNA Replication

WebThe S phase, short for synthesis phase, is a period in the cell cycle during interphase, between G1 phase and the G2 phase. Following G1, the cell enters the S stage, when DNA synthesis or replication occurs. At the beginning of the S stage, each chromosome is composed of one coiled DNA double helix molecule, which is called a chromatid. WebIn the S phase (synthesis phase), DNA replication results in the formation of two identical copies of each chromosome—sister chromatids—that are firmly attached at the centromere region. At this stage, each … WebThe attachment between sister chromatids is tightest at the centromere, a region of DNA that is important for their separation during later stages of cell division.

Web18 nov. 2024 · The sister chromatids are attached to spindles that originate from the opposite centrosome, linking the two together. Figure 3 – Prometaphase Metaphase At this stage, the chromosomes align upon a theoretical line known as the metaphase plate. The centrosomes have finished moving and are located at opposite ends of the cell. WebThe sister chromatids are identical at this stage. Homologous chromosomes pair in prophase I, forming tetrads. The tetrads then cross over, exchanging genetic material. Then, the genetically-mixed tetrads line up on the metaphase plate and are separated in anaphase I.
