Answer 2

the region of a chromosome to which the microtubules of the spindle attach, via the kinetochore, during cell division

Centromere Positions. The position of the centromere relative to the ends helps scientists tell chromosomes apart. Centromere position can be described three ways: metacentric, submetacentric or acrocentric. In metacentric (met-uh-CEN-trick) chromosomes, the centromere lies near the center of the chromosome.
