Kinetochore (Kinetochoiv)

A kinetochore is a region of a chromosome that links chromosomes to the spindle during cell division. The kinetochore ensures the attachment of spindle microtubules to the centromere of the chromosome. Thanks to this, during mitosis or meiosis, chromosomes can move towards the poles of the cell. Thus, kinetochores play an important role in the segregation of chromosomes into daughter cells.

The term kinetochore is often used as a synonym for centromere, the region of the chromosome to which the spindle strands are attached. However, strictly speaking, a kinetochore is a protein complex that forms at the centromere and ensures the connection of chromosomes with the spindle.

A kinetochore is a region of a chromosome that serves as the site of attachment of spindle filaments during mitosis or meiosis. The kinetochore forms a protein complex that connects the chromosome with the microtubules of the spindle, ensuring the correct segregation of chromosomes into daughter cells.

A kinetochore is also known as a centromere, a structure that divides a chromosome into two parts, or chromatids. Centromere and kinetochore are functionally identical; these terms can be used interchangeably to refer to the region of the chromosome responsible for attachment to the spindle.
