Acrocentric is a term used to describe chromosomes that have their centromere located near one end, resulting in one long arm and one short arm. Some synonyms for acrocentric include submetacentric, telocentric, and acrocentric-like. Submetacentric chromosomes also have the centromere located closer to one end, but their arms are not as dramatically different in length as acrocentric chromosomes. Meanwhile, telocentric chromosomes have their centromere located at the very end, resulting in only one arm. Acrocentric-like chromosomes have their centromere located closer to the middle, but still not quite at the center, resulting in slightly unequal arms. These different terms can be useful in identifying and characterizing specific chromosome types in various organisms.
