What does kinetochore do?
The kinetochore is a protein structure located at the centromere of a chromosome. It plays a crucial role in cell division by attaching the chromosome to the mitotic spindle during mitosis and meiosis, ensuring that the genetic material is evenly distributed between daughter cells.
Describe the structure and function of the spindle during mitosis?
Spindle fibers are necessary in mitosis as they help in bringing half the number of chromosomes on each side of the cell, so that when the cell divides, the chromosomes are distributed equally in both the daughter nuclei.
Centrioles are cell structures involved primarily in?
Centrioles are cell structures primarily involved in organizing the microtubules that make up the cell's cytoskeleton. They are also crucial for cell division, aiding in the formation of the mitotic spindle that helps separate chromosomes during cell division.
Where do spindle fibers attach to chromosomes?
I am at least 70% sure that they attach to the centriole which binds the chromosome together.Centrioles do not have much to do with chromosomes. Centrioles are found just floating in the cytoplasm, while chromosomes are in the nucleus. Chromatins, strands the chromosomes are make up of, are connected by the centromere. Therefore the spindle fibers probably attach to chromosomes in the nucleus, though I, as well, am not entirely sure.
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.
What structure is most closely associated with the production of the mitotic spindle?
The centrosome is most closely associated with the production of the mitotic spindle. It is responsible for organizing the microtubules that make up the spindle fibers during cell division.
The mitotic spindle formation depends upon?
The formation of the mitotic spindle depends upon the proper assembly and organization of microtubules, which are dynamic protein fibers that make up the spindle apparatus. Microtubules are regulated by microtubule-associated proteins that help facilitate their polymerization and depolymerization processes. Additionally, motor proteins are essential for moving the chromosomes to their correct positions during mitosis.

The fiber-like proteins units that make up the cells cytoskeleton the mitotic spindle and the centrioles in animal cells are?
The fiber-like protein units that make up the cell's cytoskeleton, mitotic spindle, and centrioles in animal cells are called microtubules. These tubular structures play crucial roles in cell division, cellular organization, and structural support.
What do centrioles produce?
Centrioles are involved in producing the microtubules that make up the mitotic spindle during cell division. They help organize and separate chromosomes during mitosis and are essential for cell division.

The assembling of microtubules that make up the spindle fibers occurs?
in prophase
What do spindle fibers and chromosomes form?
make copies of cells - mitosis

microtubules
