Use the Genetic Code below to help you answer the following questions. The nucleotide sequence of a hypothetical eukaryotic gene is: 3'- CCC CAT CAG TCA AGG GAA - 5' a. Provide the mRNA of the non-mutated gene. b. Provide the linear amino acid sequence of the non-mutated gene. üü c. Examine the mutated DNA sequence below. What would be the sequence of the mRNA? ü Mutated DNA sequence: 3' CCC CAC AGT CAA GGG AA 5' d. Provide the linear amino acid sequence of the mutated gene and identify the type of mutation. e. Comment on the consequences of this type of mutation?
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.
