I was reading about cell biology and came across the term extranuclear functions.

Oh, I've heard about that! It refers to things happening outside the cell nucleus, right?

Exactly! It’s fascinating how much occurs in those extranuclear regions.

Root Explanation

Extranuclear → It is formed from "extra-" (meaning outside) and "nuclear" (from Latin "nucleus", meaning kernel or core). The word "extranuclear" refers to something that is located outside the nucleus of a cell.

Memory Tip

Think of something that is 'outside' ('extra-') the 'core' ('nucleus') — that's why extranuclear means outside the nucleus.
