Not exactly. The centromeres are areas of DNA where the two sister chromatids touch. The spindle fibers actually bind to the kinetochore, a structure found on the chromosomes.

What structure acts as a scaffolding for chromosomal attatchment and movement?
Spindle acts as a scaffolding for chromosomal attachment and movement. Chromosomes attach to the spindle fibers by undivided structures called centromeres.
What happens to chromosomes after mitosis?
Cells are moved forward through the chromosomes and attached into the spindle fibers. The nuclei of the cell dissolves to make room for the spindle fibers.
Cell structures made of individual microtube fibers that are involved in moving chromosomes during cell division are called?
spindle fibers
What are the spindle fibers eventually used for?
Spindle fibres are tiny tube-like structures made of protein to which chromosomes attach during cell division.
What are the two most important structures involved in moving chromosomes during mitosis?
Centromeres and spindle fibers..Prophase: During cell division small structures called centromeres move to opposite ends of a cell.Prometaphase: These centromere structures produce spindle fibers that attach to the chromosomes' kinetochores (where the sister chromatids are joined together with bundles of proteins). Other spindle fibers attach to each other at the center.Metaphase: Tension is applied to the fibers, this causes the chromosomes to align along the center of the cell.Anaphase: The fibers pull the chromosomes apart and towards the centromeres at each end of the cell.Telophase: chromosomes arrive at ends and spindle fivers disappear.

Cells are moved forward through the chromosomes and attached into the spindle fibers. The nuclei of the cell dissolves to make room for the spindle fibers.
During metaphase the centrometers attach to what structures?
In animal cells, during metaphase stage of the cell cycle, the centrioles attach to spindle fibers. These spindle fibers are also attached to the chromosomes which are now aligned at the metaphase plate.
Cell structures made of individual microtube fibers that are involved in moving chromosomes during cell division are called?
spindle fibers
What is centride?
It is a T shaped structure with spindle fibers attached to it. The spindle fibers reach out to grab chromosomes during the cell cycle.
During metaphase the chromosomes become attached to the what fibers by means of their what?
spindle fibers, and centromere
What is the middle of the mitotic spindle?
In the middle of mitotic spindle are the duplicated chromosomes held by kinetochores. These are protein structures are involved in pulling apart the sister chromatids.
What are the spindle fibers eventually used for?
Spindle fibres are tiny tube-like structures made of protein to which chromosomes attach during cell division.
What is an area where the chromosome are attached?
The chromosomes are attached at their centromeres, which in turn attach to spindle fibers when being pulled apart during mitosis.

What is a cytoskeletal that pulls chromosomes apart?
CentriolesCentrioles are log-like structures that appear during cell division in animal cells and pull the chromosomes apart.
Do external regulators prevent the cell from entering anaphase until its chromosomes are attached to the mitotic spindle?
yes
