Spindle fibers vs microtubules

WebThe 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. The spindle grows between the centrosomes as they move … In mitosis, the nuclear DNA of the cell condenses into visible chromosomes … Just like our body consists of (or is composed of ) cell, every spindle fibre … WebMicrotubules form a spindle apparatus by involving in the chromosomal segregation during meiosis and mitosis. Microtubules are nucleated in the centromere which is the MTOCs (microtubule organizing centers) to form the spindle apparatus. Microtubules occur in basal bodies, cilia/flagella, centrioles, astral rays, and spindle fibers.

WebSep 1, 2024 · Microtubules form spindle fibers that extend from each centrosome, thereby separating centriole pairs and elongating the cell. You can think of these fibers as a newly paved highway for the replicated chromosomes to move into the newly formed cell. In this analogy, the replicated chromosomes are a car along the highway. ...
