sequence of a eukaryotic gene's DNA that is not translated into a protein
"Scientists removed the intron from the DNA sequence to ensure only the coding regions were translated into a functional protein."
A portion of a split gene that is included in pre-RNA transcripts but is removed during RNA processing and rapidly degraded.
"The researcher noticed that mutations within the intron were causing the cell to retain faulty sequences instead of splicing them out before protein synthesis began."
