chromosomes stop moving towards the pole in what phase

During prometaphase, phosphorylation of nuclear lamins by M-CDK causes the nuclear membrane to break down into numerous small vesicles. Overview of the Stages of Meiosis - ThoughtCo Centrioles are not present in the centrosomes of many eukaryotic species, such as plants and most fungi. The chromosomes become even more condensed, so they are very compact. At the end of the meiotic process, four daughter cells are produced. Use the diagram to answer questions 1-7. Mistakes in the duplication or distribution of the chromosomes lead to mutations that may be passed forward to every new cell produced from the abnormal cell. Prophase Figure 3:Mitosis: Overview of major phases. The spindle tubules then shorten and move toward the poles of the cell. Nice question. portion of interphase. How are the ends of chromosomes replicated? Chromosomes stop moving toward the poles Chromosomes line up in the center of the cell. What are the phases of mitosis? enabling sperm to swim!). What phase of meiosis is it when the spindle fibers pull homologous pairs to the opposite end of the cell? During which phase of mitosis do sister chromatids line up at the metaphase plate? a. metaphase b. prophase c. anaphase d. interphase e. telophase, During what phase of meiosis does crossing over occur? Remember that when replicating in interphase, the chromosome number DOES NOT CHANGE. Polar fibers (microtubules that make up the spindle fibers) continue to extend from the poles to the center of the cell. A new nuclear membrane forms around the chromosomes. Which of the following occurs during anaphase I? Cytokinesis in an animal cell: an actin ring around the middle of the cell pinches inward, creating an indentation called the cleavage furrow. Microtubules rapidly assemble and disassemble as they grow out of the centrosomes, seeking out attachment sites at chromosome kinetochores, which are complex platelike structures that assemble during prometaphase on one face of each sister chromatid at its centromere. Is this also a phase of mitosis? a. prophase b. prometaphase c. metaphase d. anaphase e. telophase, In what phase of meiosis does an independent assortment of homologous chromosomes occur? During prophase, the parent cell chromosomes
