查询词典 a bond

The splicing reaction involves two transesterification steps which ligate the exons together and release the intron as a branched lariat structure containing a 2'5' bond with a conserved A residue in the branchpoint sequence. The splicing reactions require snRNPs and accessory proteins that assemble into a splicesome at the intron to be removed.
