Best Answer

The centromere is the part of a chromosome that links the sister chromatids together. There are two types of centromeres. Regional centromeres have DNA sequences that contribute to, but do not define function. Point centromeres are smaller and more compact, but the DNA sequences are necessary and sufficient to specify the centromere's identity and function.
