Answer :
Driving chromosome motion (microtubules) The bipolar spindle, which is composed of microtubules and related motor proteins, is the most noticeable structure in a mitotic cell. It is responsible for moving the chromosomes and causing their segregation.
What about chromosome?
- A chromosome is a long DNA molecule that houses all or some of the genetic code of an organism.
- The very long, thin DNA fibers in most chromosomes are covered with packing proteins; in eukaryotic cells, the histones are the most significant of these proteins.
- The chromosomes, which have already replicated their DNA and are oriented across the middle of the cell, are attached to the microtubules as mitosis continues.
- After then, the spindle tubules shorten and migrate in the direction of the cell's poles.
- The one copy of each chromosome is pulled along by them as they migrate to the opposing poles of the cell.
- The mitotic spindle, a structure made up of microtubules and related proteins, aids in the movement of chromosomes.
- To align the chromosomes and draw the sister chromatids apart, spindles attach to and stretch from centrioles on each of the two poles (or sides) of the cell.
- Radiation exposure and/or TEs have both been linked to chromosomal rearrangements as possible causes of them.
- By using Giemsa staining, FISH, or chromosomal painting, several of these rearrangements can be found.
