Definition

A type of chromosomal material that is active in gene expression and appears lighter when stained with certain dyes.

Conversation

I was reading about euchromatin in my biology class today.

Oh really? What did you find interesting about it?

It's fascinating how euchromatin is the part of the chromatin that's actively involved in gene expression.

That makes sense! It's amazing how our genes are regulated.

Root Explanation

Euchromatin → It is formed from "eu-" (from Greek "eu", meaning good or well) and "chromatin" (from Greek "chroma", meaning color). The term refers to the part of chromatin that is less condensed and is associated with active gene expression, hence 'good' or 'well' in terms of functionality.

Memory Tip

Think of 'eu-' meaning 'good' and 'chromatin' relating to 'color' — euchromatin is the 'good' part of chromatin that is actively involved in gene expression.
