The centromere is essential for the correct segregation of chromosomes during cell division. It is the point where the chromosome attaches to the spindle fibers.
Tips
A common mistake is confusing the centromere with other parts of the chromosome like telomeres or chromatids. Remember, the centromere is specifically the region responsible for chromosome segregation.
