In one form of thalassemia, the mutation of a single base from G to A generates a new 3' splice site that is farther upstream from the normal site. The normal and mutated sequences show the sense DNA strands of a normal and thalassemic patient. 5' CCTATTGGTCTATTTTCCACCCTTAGGCTGCTG 3' Normal 3' end of intron 5' CCTATTAGTCTATTTTCCACCCTTAGGCTGCTG 3' 3' end of mutated intron New start of reading frame What is the amino acid sequence of the extra segment of protein synthesized in a thalassemic patient that results from the aberrant splicing? Use the codon table and write the peptide sequence using three-letter amino acid abbreviations separated by hyphens.
