The term intron refers to both the DNA sequence within a gene and the corresponding sequence in the unprocessed RNA transcript. As part of the RNA processing pathway, introns are removed by RNA splicing either shortly after or concurrent with transcription. Introns are found in the genes of most organisms and many viruses.
Types of RNA Processing. There are three main types of RNA processing events: trimming one or both of the ends of the primary transcript to the mature RNA length; removing internal RNA sequences by a process called RNA splicing; and modifying RNA nucleotides either at the ends of an RNA or within the body of the RNA.
