Chromosomes (article) Cell cycle Khan Academy
WebChromosomes are not randomly organized in a cell’s nucleus. Instead, chromosomes appear to occupy specific subdomains within the nucleus in which they reside. WebThe chromosomes start to condense (making them easier to pull apart later on). The mitotic spindle begins to form. The spindle is a structure made of microtubules, strong fibers that are part of the cell’s “skeleton.” Its job is to organize the chromosomes and move them around during mitosis. highlight glazing
