Spindle fibers loop around the kinetochore of a chromatid to ensure proper attachment and alignment during cell division. This arrangement allows the fibers to exert force on the chromatids, facilitating their movement toward opposite poles of the cell during anaphase. The looping mechanism also provides stability and enhances the accuracy of chromosome segregation, reducing the risk of errors that could lead to aneuploidy.

What is rotating spindle?
A rotating spindle is a cylindrical rod or shaft that rotates around its central axis. It is commonly used in machinery and tools to hold and spin a workpiece for shaping, cutting, or drilling operations. The rotation of the spindle allows for precise and controlled machining processes.
How can I make spinning wheels?
To make spinning wheels, you will need a circular frame, a spindle, and a flyer. Attach the spindle vertically in the center of the frame and connect the flyer to the spindle. Add hooks to the flyer for the yarn to wrap around. Turn the wheel to spin the flyer, which will twist the fibers into yarn.
Material around centrioles from which the mitotic spindle grows?
The pericentriolar material (PCM) is a dense network of protein fibers and complexes located around centrioles. It serves as the primary site from which microtubules of the mitotic spindle nucleate and grow during mitosis. The PCM plays a crucial role in organizing and anchoring microtubules to ensure proper spindle formation and chromosome segregation.
How one division of the nucleus a new spindle forms around each group of chromosomes?
telophase
What part of the chromosomes do the spindle fibers attach to in order to move the chromosomes around?
Spindle fibers attach to the chromosomes at a region called the centromere, which is the constricted area where sister chromatids are joined together. Specifically, the spindle fibers connect to protein structures called kinetochores that form on the centromere during cell division. This attachment allows the spindle fibers to exert forces that move the chromosomes during mitosis and meiosis.
What is a seventh grade word for kinetochore?
I can only find spindle microtubules for kinetochore. Words and concepts get older as you get older, there just isn't anyway around it.
How do you perform mitosis?
Mitosis is composed of 5 steps: 1)prophase 2) metaphase 3) anaphase 4) telophase 5) cytokinesis Beginning from prophase, the nuclear envelope and nucleolus begin to dissolve and the spindle fibers start to form. In metaphase, the chromosomes form a line down the middle of the chromosome and the fully formed spindle fibers attach to the kinetochore, which are in turn attached to the centromere which is holding the sister chromatids ,which make up the chromosome, together. During anaphase, the sister chromatids are pulled apart and the centromere ruptures. Each chromatid is pulled to a pole on the opposite side of the cell. Telophase is simply prophase in reverse. The nucleolus is reformed, one around each chromatid, as well as the nuclear envelope and the spindle fibers begin to dissolve. Lastly, cytokinesis is the physical separation of the cell into two daughter cells,
What is miotic spindle?
The miotic spindle moves the chromosomes around in the cell during prophase. The miotic spindle is formed by excess parts from the dismantled cytoskeleton.The spindle is initially setup outside the nucleus. p.s- im in ap biology so u can trust my answer :)

What is a spindle on a watch?
A spindle on a watch is a small cylindrical component that supports the hands of the watch. It acts as a pivot point for the hands to rotate around, allowing them to move smoothly and accurately to indicate the time. The spindle is connected to the movement of the watch, which drives the hands.
