The spindle is formed primarily from microtubules, which are protein filaments made up of tubulin dimers. During cell division, specifically mitosis and meiosis, these microtubules organize into a structure known as the spindle apparatus, which helps segregate chromosomes into the daughter cells. Additional proteins, such as motor proteins and spindle assembly factors, also play crucial roles in stabilizing and regulating the spindle's function.

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 is responsible for forming spindle during mitosis?
The centrioles within the cell form the mitotic spindle.
What joins arms together and is the place where spindle fibers attach to each chromosome?
The sister chromatids (arms) are held together by centromeres. Centromeres are the site of attachment for the spindle fibers.
Is a compound an invisible form of matter?
Its either: 1. elemnts put together 2. Atoms put together Real answer: #1
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 organelles form the asters and the spindle fibers?
The centrioles in animal cells form the asters and the spindle fibers.
What is the spindle is form?

Do the centrosomes form spindle fibers?
yes

What causes a stembody to form in animal cells?
The stembody is formed when the spindle fibers are pressed together tightly by the furrow. When the cell divides the stembody is cut into two.
What is responsible for forming spindle during mitosis?
The centrioles within the cell form the mitotic spindle.
