Chromosomes align along midline of cell
WebChromosomes become more condensed and visually discrete. Each sister chromatid attaches to spindle microtubules at the centromere via a protein complex called the kinetochore. During metaphase, all of the … WebChromosomes, consisting of sister chromatids, line up at the equator or middle of the cell during metaphase. Anaphase During anaphase, sister chromatids separate and the centromeres divide. The sister chromatids …

WebMitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase. Interphase is often included in discussions of mitosis, but interphase is technically not part of mitosis, but rather encompasses stages G1, S, and G2 of the cell cycle.
