Abstract

Most eukaryotic protein-coding genes are composed of exon and intron sequences. Intron derived sequences within primary transcripts are eliminated by ribonucleic acid (RNA) splicing. A small number of protein-coding genes are intronless; their primary transcripts are processed at their 5′ and 3′ ends like other premessenger RNAs, but no splicing is needed. Examples of intronless genes are genes for histone and interferon.
