Web• State the key functions of cell division. • Understand why cell division results in genetically identical cells. • Outline the stages in the cell cycle including interphase (G1, S, G2) mitosis and cytokinesis. • Describe the events that occur in the phases of mitosis (prophase, prometaphase, metaphase, anaphase and telophase. WebMay 3, 2024 · Figure 10.3.1. 5: Cell A is in prometaphase. The chromosomes are no longer contained within a nuclear envelope. The spindle fibers are attaching to the kinetochores, but the chromosomes have not yet been pulled into a line. Cell B is in metaphase and the chromosomes are loosely aligned on the metaphase plate.

WebIn prophase, the nucleolus disappears and chromosomes condense and become visible. In prometaphase, kinetochores appear at the centromeres and mitotic spindle microtubules attach to kinetochores. In metaphase, … WebThe cell cycle has two major phases: interphase and the mitotic phase ( Figure 6.3 ). During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are …
WebPrometaphase I The key event in prometaphase I is the attachment of the spindle fiber microtubules to the kinetochore proteins at the centromeres. Kinetochore proteins are multiprotein complexes that bind the centromeres of a chromosome to the microtubules of the mitotic spindle. WebChromosomes in the cell’s nucleus will condense, and chromatin coils up.; Short rods will appear and become visible. The centrioles will divide. The late phase/prometaphase:. The nuclear membrane breaks down, and the nucleolus forms parts of several chromosomes.
