What will these spindle fiber eventually be used for?
There are six phases of mitosis (a way which allows cell to reproduce itself so that organisms can grow). In this process, DNA is coiled into chromosomes. In the second phase, the spindle fibers attach themselves to centromere - centromere is a part of chromosome linking two sister chromatids (2 chromsatids make one chromosome). In the fourth phase, these spindle fibers shorten themselves and the sister chromatids are physically separated by the action. This way the two diploid daughter cells produced in mitosis have 46 chromosomes each.
During which phase of mitosis are chromosomes attaching to the spindle?
Chromosomes attach to the mitotic spindle during the metaphase of mitosis. Part of the answer depends on how you define the stages of mitosis and not everybody does this the same way. The short answer is all of them.
The part of a chromosome that attaches itself to the cell's spindle fibers during mitosis is called the?
The part of a chromosome that attaches to the cell's spindle fibers during mitosis is called the centromere. This structure plays a crucial role in ensuring that chromosomes are properly segregated into daughter cells during cell division. The centromere is responsible for the movement of chromosomes by serving as the attachment site for spindle fibers, which pull the sister chromatids apart.
What part of the cell separates the chromosomes during cell division or reproduction?
During cell division, the part of the cell that separates the chromosomes is the spindle apparatus, which is made up of microtubules. These microtubules extend from the centrosomes at opposite poles of the cell and attach to the kinetochores on the chromosomes. As the spindle fibers contract, they pull the sister chromatids apart, ensuring that each daughter cell receives an identical set of chromosomes. This process occurs during both mitosis and meiosis.
What part of the chromosomes do the spindle fibers attach to in order to move the chromosomes around?
Spindle fibers attach to the chromosomes at a region called the centromere, which is the constricted area where sister chromatids are joined together. Specifically, the spindle fibers connect to protein structures called kinetochores that form on the centromere during cell division. This attachment allows the spindle fibers to exert forces that move the chromosomes during mitosis and meiosis.
What function do spindle fibers perform during cell division?
Spindle fibers are responsible for separating and moving chromosomes during cell division. They attach to the chromosomes at the kinetochore region and help pull them to opposite poles of the cell during both mitosis and meiosis. This ensures the accurate distribution of genetic material to daughter cells.
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.

Microtubules

What is the meaning of the word Kinetochore?
"Kinetochore" refers to a specific part of the centromere. It is a specialized structure that microtubular spindle fibers attach to during mitosis and meiosis.
Can you explain 'prophase' in one sentence?
Yes, prophase is a part in the cell cycle of mitosis where spindle fibers form and attach to chromosomes.
What are chromosome pairs attached to?
Pairs of chromosomes are not attached. Before mitosis chromosomes replicate themselves, these twin identical chromosomes are attached at the centromere. before cell division the cell has 46 chromosomes (23 pairs) but has 2 copies of each individual chromosome called chromatids,(making a total of 92 chromosones, 46 for each daughter cell) which are joined at the centromere giving the characteristic X shape. Pairs are not joined, chromatids are.
