Explain sister chromatids
WebFeb 4, 2024 · These sister chromatids carry identical DNA and are joined at the center (in the middle of the “X” shape) at a point called the centromere. The centromeres will serve as anchors that’ll be used to pull the sister chromatids apart during a later phase of mitosis. And that’s what’s happening inside the nucleus during prophase! After the ... Webchromosomes and sister chromatids using pop beads or pipe cleaners. The teacher will use the chromosomes to model how their number changes as a cell goes through mitotic or meiotic division. Images of the cell cycle, and stages of mitosis and meiosis will be projected and referred to as the demonstration occurs.
