Chromosomes attached to the spindle fibers by undivided structures is called what?
Name of the Undivided Structures"The centromeres enable chromosomes to attach to spindle fibers." 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.
Which phase of mitosis do chromosomes line up at the equator of the spindle?
Chromosomes line up at the equator of the spindle during the metaphase stage of mitosis. This is when the chromosomes are maximally condensed and are attached to the spindle fibers at their centromeres.
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.
Which work together to move chromosome during cell division?
During cell division, particularly mitosis and meiosis, the main structures that work together to move chromosomes are the spindle fibers and the centromeres. Spindle fibers, which are composed of microtubules, attach to the centromeres of the chromosomes and help align them at the cell's equatorial plane. As the cell divides, these fibers pull the sister chromatids apart toward opposite poles of the cell, ensuring that each daughter cell receives an identical set of chromosomes.
What separates sister cells during mitosis?
During mitosis, sister chromatids are separated by the spindle fibers attached to the centromeres of each chromatid. This process ensures that each daughter cell receives an identical set of chromosomes as the parent cell divides.
Chromosomes centromeres are attached to the kinetochore fibers?
Prophase
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 structure are spindles attached to that help pull the paired chromosomes apart?
Spindle fibers attach to the centromeres on the sister chromatids.
Chromosomes attached to the spindle fibers by undivided structures is called what?

Chromosomes line up at the equator of the spindle during the metaphase stage of mitosis. This is when the chromosomes are maximally condensed and are attached to the spindle fibers at their centromeres.
To which part of the centromere do mitotic spindle fibers attach during prometaphase?
The centromeres of chromosomes attach to the spindle fibers during metaphase. The spindle fibers bring about the separation of sister chromosomes to the opposite poles. When spindle fibers do not attach to the centromeres, the doubling of chromosomes leads to polyploidy in the cell.

What causes the dancing of chromosomes in anaphase?
So that the cell can divide into two identical daughter cells, each with its own genetically identical nucleus.
During this stage of mitosis, when do the chromosomes become attached to the spindle fibers?
During metaphase of mitosis, the chromosomes become attached to the spindle fibers.
During metaphase the centrometers attach to what structures?
During metaphase, the centromeres of chromosomes attach to spindle fibers (microtubules) that extend from opposite poles of the cell. This attachment helps properly align the chromosomes along the metaphase plate in the center of the cell before they are separated in anaphase.
What structures pull the chromosomes apart?
The spindle fibers, which are composed of microtubules, pull the chromosomes apart during cell division. These fibers attach to the centromeres of the chromosomes and help guide them to opposite poles of the cell during mitosis or meiosis.
During prophase, when do spindle fibers become attached to the chromosomes?
Spindle fibers become attached to the chromosomes during prophase in the early stages of cell division.
