What term is used to describe the structure at which each fibers attach to a chromosome?
The region is called the centromere.
What else can I help you with?
What joins chromosomes arms together and is the place where spindle fibers attach to each chromosome?
The structure that joins chromosome arms together is called the centromere. The centromere is essential for proper chromosome segregation during cell division and is the point where spindle fibers attach to the chromosome to facilitate this process.
Fibers in the spindle that attach to the centromere of the chromosomes?
These are called kinetochore fibers. They are microtubules that attach to the kinetochore, a protein structure on the centromere of the chromosome, helping to move the chromosomes during cell division.
What forms during prophase to later attach and move chromosome?
Spindle fibers
When during mitosis do chromosomes attach to spindle fibers?
Chromosomes attach to spindle fibers during metaphase of mitosis. This is when the chromosomes align at the cell's equator, forming a metaphase plate. The spindle fibers attach to the centromere region of the chromosomes.
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.
Cellular structure to which the chromosomes attach?
Centromere. It is a region on a chromosome where the kinetochore forms, allowing for attachment to spindle fibers during cell division, ensuring proper segregation of chromosomes.
What is the structure called that holds two chromatids together?
The structure that holds two chromatids together is called a centromere. It is a region of the chromosome where the two sister chromatids are attached and where the microtubules of the spindle fibers attach during cell division.
What term is used to describe the structures at which each fibers attaches to a chromosome?
The region is called the centromere.
Where do microtubules attach to chromosomes during mitosis?
Microtubules attach to chromosomes at the kinetochore, a protein structure located at the centromere region of each chromosome. This attachment ensures accurate segregation of chromosomes during mitosis.
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.
Distinguish between kinetochore fibers and polar fibers?
Kinetochore fibers are microtubules that attach to the kinetochore region of a chromosome during cell division, helping to pull the chromosome apart. Polar fibers, on the other hand, are microtubules that interact with each other and help push the poles of the cell apart during cell division, providing structural support.
How do spindle fibers attach to chromosomes and line them up during cell division?
Spindle fibers attach to chromosomes by binding to specific protein structures called kinetochores located on the centromere of each chromosome. The spindle fibers then exert tension on the chromosomes, aligning them along the cell's equator during cell division.
