Describe the phenotype of the following E. coli mutants when grown in two different media: glucose only and lactose only. Explain the reasoning behind your answer. a. A strain with a mutation in the gene encoding the lac repressor; the mutant repressor cannot bind allolactose. b. A strain with a mutation in the gene encoding CAP; the mutant form of CAP binds but cannot release cAMP. c. A strain in which the Shine-Dalgarno sequence has been deleted from the gene encoding adenyl cyclase.
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.
