QUESTION 3 Imagine that you repeat the tRNA Selection experiment with modifications as follows: 1. Synthesize mRNA containing A's and G's only (poly-AG in random order). 2. Convert the amino acid Glutamic acid (Glu) on its tRNA to the amino acid Glutamine (Gln) as shown below. 3. Mix your poly-AG RNA, your artificial tRNA, and cell extract (contains ribosomes, amino acids, all normal tRNAs, and the energy source for translation). Phe Tyr 5' of of GAA GAA Glutamic acid (Glu) is encoded by GAA and GAG, while Glutamine (Gln) is encoded only by CAA and CAG. What does the outcome of this experiment tell us about translation? O Multiple codons code for each amino acid. An amino acid is selected based on the identity of the tRNA. The ribosome does the translation, i.e. it selects the amino acid regardless of the identify of the tRNA. The ribosome reads mRNA 3 bases at a time.

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.
