WebbIn this case, the duplicated chromosomes (only one set of them) line up on the metaphase plate with divided kinetochores attached to kinetochore fibers from opposite poles. During anaphase II, as in mitotic anaphase, the kinetochores divide and one sister chromatid—now referred to as a chromosome—is pulled to one pole while the other … WebbMitosis plays an important role in body processes like tissue repair and growth. 2-Microtubules are essential in nuclear division, or mitosis. They provide the framework for seperating duplicated chromosomes during mitosis in plants. Animals undergo cytoplasmic division by creating a cell wall between daughter cells that pinches them in …

Webb15 okt. 2024 · During meiosis, chromosomes are replicated once in S phase (just like mitosis) into sister chromatids, but the cell divides twice. As with mitosis, the first step in this process is DNA replication, so that each of the 46 chromosomes exists as a duplicated sister chromatid. What do cells undergo mitosis? WebbThe number of chromosomes in each daughter cell will match that of the parent cell if the process is error-free and each daughter cell receives the same set of chromosomes as the parent cell. As a result, each daughter cell produced after mitosis will have 20 chromosomes if the parent cell had 20 before mitosis.
