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 structures allow chromosomes to separate and move during mitosis?
The spindle apparatus, made up of microtubules, plays a key role in chromosome separation and movement during mitosis. The centrosomes help organize and control the spindle apparatus. The kinetochores, located at the centromere of each chromosome, attach to the microtubules and facilitate chromosome movement.
What is the region of a chromosome holding the two double strands of replicated DNA together called?
The region of a chromosome holding the two double strands of replicated DNA together is called a centromere. The complex of DNA and protein that makes up eukaryotic chromosome is properly called chromatin.
What is the function of centromere?
The centromere is a region of a chromosome that helps in the process of cell division. It plays a crucial role in ensuring that each daughter cell receives the correct amount of genetic material. The centromere also serves as the attachment point for spindle fibers during mitosis and meiosis.
What is the region of a chromosome where two sister chromatids attach?
The region of a chromosome where two sister chromatids attach is called the centromere. It appears as a constricted area on the chromosome, serving as a site for protein binding and attachment of spindle fibers during cell division. The centromere plays a crucial role in ensuring proper segregation of chromosomes during mitosis and meiosis.
The phase of mitosis in which microtubles connect the centromere of each chromosome to the poles of the spindle is?
Metaphase
What is the Phase of mitosis in which microtubules connect the centromere of each chromosome to the poles of spindle?
a microscopically small tuble, it is the introcellular support of the cytoskeleton and also helps in transport of certain protein molecules.
What region of the chromosome serves as the attachment site for microtubules during Cell division?
The kinetochore is the region of the chromosome that serves as the attachment site for microtubules during cell division. It is a protein structure that forms on the centromere of a chromatid. Kinetochore microtubules connect the chromatids to the mitotic spindle to aid in the separation of chromosomes during mitosis.
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.

The kinetochores, located at the centromere of each chromosome, attach to the microtubules and facilitate chromosome movement.
What guides the chromosomes movement during mitosis?
The spindle fibers, composed of microtubules, help guide the movement of chromosomes during mitosis. The microtubules attach to the centromere region of the chromosomes and pull them towards opposite poles of the cell. This ensures that each daughter cell receives the correct number of chromosomes.
The region of the chromosome that holds the two sister chromatids together during mitosis?
Centromere

During mitosis microtubles attach to chromosomes at the?
kinetochores, which are protein structures found at the centromere of each chromosome. The microtubules attach to the kinetochores and help to accurately separate the duplicated chromosomes into two daughter cells during cell division.
What is the function of centromere?
