Spindle fibers during anaphase
WebTwo separate classes of movements occur during anaphase. During the first part of anaphase, the kinetochore microtubules shorten, and the chromosomes move toward the spindle poles. During the ... WebTo begin, let’s explore the different stages of mitosis. Prophase is the first stage of mitosis. In prophase, chromosomes condense and become visible. spindle fibers emerge from the centrosomes. nuclear envelope breaks down. nucleolus disappears. Prometaphase is the second stage of mitosis. In prometaphase,

WebApr 13, 2024 · During cell division, chromosome segregation is considered to be driven by a spindle consisting of microtubules. Firstly, the microtubules capture and align the chromosomes at the spindle center. The chromosomes are segregated and moved to the poles of spindles during anaphase. Webanaphase-During anaphase, sister chromatids separate and daughter chromosomes migrate to opposite poles. Spindle fibers attach to kinetochores during _____. prometaphase …
WebDuring anaphase one, there are homologues that have been positioned on the metaphase plate during the previous phase, metaphase. In anaphase, these homologues are pulled on by the mitotic spindle, being pulled apart. After the homologues are separated, the spindle fibers pull them into opposite poles of the cell.
