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.
Mitotic spindle fibers attach to the kinetochore region of the centromere during prometaphase. The kinetochore is a protein structure on the centromere that serves as the attachment site for spindle fibers, allowing for the movement of chromosomes during mitosis.
During metaphase the centromeres attach to the duplicated chromosomes. ~Hope this helps~:)

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 happens during prometaphase?
During prometaphase of mitosis, the nuclear envelope breaks down, allowing the chromosomes to become free in the cytoplasm. The mitotic spindle, made of microtubules, forms and attaches to the centromeres of the chromosomes. The chromosomes are then moved and aligned at the center of the cell in preparation for separation during metaphase.
What is kinetechore?
A kinetochore is a protein structure that forms on a chromatid during cell division. It plays a crucial role in cell division by helping to attach the chromatid to the mitotic spindle, ensuring proper segregation of chromosomes into daughter cells.
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.
The phase of mitosis in which microtubules connect the centromere of each chromosome to the poles of the pindle?
The phase of mitosis in which microtubules connect the centromere of each chromosome to the poles of the spindle is called metaphase. This alignment ensures that the chromosomes are properly positioned for separation during anaphase.
When do microtubules attach to kinetochores?
Microtubules attach to kinetochores during prometaphase of mitosis, forming the mitotic spindle apparatus. This attachment is crucial for proper chromosome alignment and segregation during cell division.
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 are protein strands that attach to the centromere?
Spindle fibers.

During prometaphase of mitosis, the nuclear envelope breaks down, allowing the chromosomes to become free in the cytoplasm. The mitotic spindle, made of microtubules, forms and attaches to the centromeres of the chromosomes. The chromosomes are then moved and aligned at the center of the cell in preparation for separation during metaphase.
At prometaphase of mitosis?
At prometaphase of mitosis, the nuclear envelope breaks down, allowing the condensed chromosomes to fully capture and attach to the mitotic spindle through their kinetochores. This stage is marked by the movement of chromosomes towards the center of the cell in preparation for proper alignment at the metaphase plate. Microtubules from opposite spindle poles attach to each sister chromatid of the chromosomes.
When does the spindle attach to the kinetochores?
The spindle attaches to the kinetochores during prometaphase, where the microtubules from the spindle apparatus interact with the kinetochores on sister chromatids. This attachment is essential for proper chromosome alignment and segregation during cell division.
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.
What is the Phase of mitosis in which microtubules connect thecentromere of each chromosome to the poles of spindle?
The phase you are referring to is called prometaphase. During prometaphase, the microtubules attach to the kinetochores at the centromere of each chromosome, allowing them to move and align properly along the metaphase plate in preparation for separation during anaphase.
What is kinetechore?
A kinetochore is a protein structure that forms on a chromatid during cell division. It plays a crucial role in cell division by helping to attach the chromatid to the mitotic spindle, ensuring proper segregation of chromosomes into daughter cells.
What part of the chromosome is the spindle apparatus attach?
The spindle apparatus attaches to the centromere region of the chromosome. This is where the kinetochore proteins are located, which help in the attachment of spindle microtubules to the chromosome during cell division.
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.
