WebIn contrast, asymmetrical exons—that is, exons flanked by different-phase introns—cannot be alternatively spliced because such alternative splicing will throw the normal open reading frame (ORF) out of frame beyond the 3′-splice site (Figure 1.5). Such frameshift results in the creation of premature stop codon and truncation of the ORF. WebA group II intron-type open reading frame from the thermophile Bacillus (Geobacillus) ... The gene codes for an open reading frame (ORF) similar to the ORFs encoded by group II introns found in bacteria. The gene was cloned and overexpressed in Escherichia coli, and its protein product was partially purified.
