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

Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
