What else can I help you with?
Are Centrioles necessary for spindle formation?
Centrioles are important for spindle formation in animal cells, as they help to organize the microtubules that make up the spindle apparatus. However, some cells, such as plant cells, can form functional spindles without centrioles.
What is the site of spindle formation?
Spindle formation occurs in the centrosome, a cellular organelle that serves as the main microtubule-organizing center in animal cells. The centrosome helps to assemble and organize the microtubules that make up the spindle apparatus during cell division.
In which phase do spindle apparatus has disassembled and the spindle fibers dissolve?
Telophase
What part of the chromosome is the spindle apparatus attach?
The spindle apparatus attaches to the centromere region of the chromosome. This is where the kinetochore proteins are located, which help in the attachment of spindle microtubules to the chromosome during cell division.
When what phase does a DNA spindle form?
A DNA spindle, or spindle apparatus, forms during the prophase stage of mitosis and meiosis. Specifically, in prophase, the chromatin condenses into visible chromosomes, and the spindle fibers begin to extend from the centrosomes to form the spindle apparatus, which is crucial for the separation of sister chromatids during cell division.

In which phase do spindle apparatus has disassembled and the spindle fibers dissolve?
Telophase
What provides material for spindle formation?
The centrosome, specifically the pair of centrioles within it, provides the material for spindle formation in animal cells. The centrioles duplicate during the cell cycle and serve as the organizing centers for microtubules that make up the spindle apparatus.
During which step in mitosis do the chromosomes get attached to the spindle apparatus?
During the metaphase stage of mitosis, the chromosomes become attached to the spindle apparatus.
The spindle apparatus disintegrates during .?
Telophase
What part of the chromosome is the spindle apparatus attach?
The spindle apparatus attaches to the centromere region of the chromosome. This is where the kinetochore proteins are located, which help in the attachment of spindle microtubules to the chromosome during cell division.
A fan like microtubule structure that helps separate the chromosomes is a?
the spindle
What organelles produce spindle fibers?
Centrioles. They are only found in animal cells and produce the spindle fibers during cell division (namely, Metaphase). One set is located at each pole of the cell.
When what phase does a DNA spindle form?
A DNA spindle, or spindle apparatus, forms during the prophase stage of mitosis and meiosis. Specifically, in prophase, the chromatin condenses into visible chromosomes, and the spindle fibers begin to extend from the centrosomes to form the spindle apparatus, which is crucial for the separation of sister chromatids during cell division.
What forms the pole of spindle apparatus?
Associated proteins, and any centrosomes or asters present at the spindle poles.
The framework of microtubules that appears in cell division which eventually moves the chromatids apart is called the?
spindle apparatus
