21. One form of thalassemia has a single G->A mutation in the B-globin gene at the first nucleotide in the intron. This destroys the S' splice junction. The mRNA remains unspliced, leaving nucleotide intron in place. Assuming no stop codons are introduced in the intron pro second exon would be in-frame or out of frame in the translated protein dict if the A. In frame B. Out of frame Phe Ser Ty Cys U Phe Ser Cys Leu Se Stop...
