Root Explanation

Nucleosome → It is formed from "nucleus" (from Latin "nucleus", meaning kernel or core) and "-some" (from Greek "soma", meaning body). The word "nucleosome" refers to a structural unit of a chromosome, consisting of a segment of DNA wound around a core of histone proteins, thus representing a body around the nucleus of the cell.

Memory Tip

Think of the 'nucleus' as the core part of a cell and '-some' meaning a body. This helps you remember that a nucleosome is a body that surrounds the core of DNA.
