WebBackground It is widely accepted that orthologous genes have lost or gained introns throughout evolution. However, the specific mechanisms that generate these changes have proved elusive. Introns are known to affect nearly every level of gene WebSep 24, 2024 · A lariat or loop structure is formed. Near the 3′ end of the intron, the free 5′ end of the intron connects to a branch site, a conserved sequence. U2 binds to the branch site and recruits U1 to commence the lariat. A phosphodiester bond is then created between the free 5′ G and an A at the branch site to form the lariat.
