What is introns and exons? [Ultimate Guide!]

WebIntrons are the sequences between the exons and the intron messages are spliced out by the spliceosome in the formation of the coding RNAs (mRNA, rRNA and tRNA). Although they may be considered as noncoding, some introns enhance the expression of the genes in which they are contained and on occasion do code for parts of proteins.
