Question
Solution
The mitotic spindle fibers attach to chromosomes via special structures termed kinetochores. Kinetochores are protein complexes that assemble on the centromere of each chromosome during cell division. They play a crucial role in ensuring that chromosomes are properly segregated into daughter cells. The kinetochores connect the chromosomes to the spindle fibers, which are responsible for pulling the chromosomes apart during mitosis and meiosis. This attachment is vital for the accurate distribution of genetic material, preventing errors that could lead to conditions such as aneuploidy, where cells have an abnormal number of chromosomes.
