Noncoding Sequences

Regions of DNA that do not code for proteins but can regulate gene expression and have roles in the genome's structure and function.

Introns

Non-coding sequences of DNA within a gene that are removed during RNA processing before translation into proteins.

Eukaryotic

Eukaryotic refers to organisms whose cells contain a nucleus enclosed within membranes, distinguishing them from prokaryotic organisms, which lack a membrane-bound nucleus.
