Definition

Relating to a sequence of DNA or RNA that is complementary to a specific messenger RNA, which can block the messenger RNA from being translated into protein.

Example

The researchers used antisense technology to inhibit the expression of the target gene.

Conversation

Have you heard about the new antisense therapy they're developing?

Yeah, I read something about it; it sounds promising for treating genetic disorders.

It's fascinating how antisense technology can actually target specific RNA sequences.

I know! It could change the way we approach many diseases.

Root Explanation

Antisense is formed from "anti-" (meaning against) and "sense" (from Latin "sensus", meaning feeling or perception). The word refers to a strand of nucleic acid that is complementary to a given sense strand, effectively working against the sense strand in genetic contexts.

Memory Tip

Think of 'anti-' meaning against, and 'sense' relating to perception or feeling — antisense refers to something that works against the normal sense.
