Q11: You are comparing the process of RNA splicing in an mRNA from normal and mutant cells of the same tissue. You find that the mutant mRNA is longer than the mRNA from the normal cells. Examination of the sequences of the gene encoding this mRNA reveals that there are nucleotide changes at the boundary of one of the exons in the mutant cell gene. Which of the following nucleotides would be expected to be found at the 3' end of upstream donor exons and the 5' end of downstream acceptor exons in the normal gene but not in the mutant gene? A. AG-G B. AG-AG C. CA-GA D. G-AG E. CG-G

Question
Q11: You are comparing the process of RNA splicing in an mRNA from normal and mutant cells of the
same tissue. You find that the mutant mRNA is longer than the mRNA from the normal cells.
Examination of the sequences of the gene encoding this mRNA reveals that there are nucleotide
changes at the boundary of one of the exons in the mutant cell gene. Which of the following nucleotides
would be expected to be found at the 3' end of upstream donor exons and the 5' end of downstream
acceptor exons in the normal gene but not in the mutant gene?
A. AG-G
B. AG-AG
C. CA-GA
D. G-AG
E. CG-G
