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.
DNA regions: Introns do not code for protein synthesis. Exons coding regions. RNA processing: Since mRNA transcribes intron + exon regions, the introns must be deleted from the mRNA before it leaves the nucleus. Exons are joined together and exit the nucleus and enter the cytoplasm.NA regions: Introns do not code for protein synthesis. Exons coding regions.
