Root Explanation

Centromere is formed from "centro-" (from Greek "kentron", meaning center) and "-mere" (from Greek "meros", meaning part). The word refers to the central part of a chromosome where the two sister chromatids are joined.

Memory Tip

Think of the 'center' ('centro-') of a chromosome being a 'part' ('-mere') that holds the chromatids together.
