Conversation

I read that some DNA sequences are noncoding and don't produce proteins.

Yeah, I heard about that too! They're still important for regulating genes.

Exactly! It's fascinating how noncoding regions can influence so much.

Right? They play a big role in how our genes are expressed.

Root Explanation

Noncoding → It is formed from "non-" (meaning not) and "coding" (from the root "code", which comes from Latin "codex", meaning a book or a system of symbols). The word "noncoding" refers to something that does not involve or produce a code, particularly in genetics where it describes sequences that do not code for proteins.

Memory Tip

Think of 'non-' meaning 'not' and 'coding' referring to a system of symbols or instructions. This helps you remember that 'noncoding' means something that does not produce a code.
