non-redundant

Nothing extra here

Non-redundant describes something that contains no unnecessary repetition or duplication.

In data and writing, non-redundant information appears only once, with nothing superfluous: a non-redundant database design, non-redundant phrasing.

In biology, non-redundant genes or proteins have unique functions not duplicated elsewhere in the system.
