An intron is a portion of DNA that is part of a gene but does not contain information about the amino acid sequence of a protein. In other words, this is a transcribed portion of DNA that is removed from the transcript during splicing; as a result, sequences located on both sides of the intron (exons) are combined. The nucleotide sequence corresponding to the intron is deleted from the mRNA transcribed from it during the splicing process before the protein is read (translation).
