The E. coli lacZYA región will be transcribed at a rate greater than the low basal rate if: A. glucose and lactose are both present in the growth medium, but there's a defect in the cells ability to synthesize cAMP B. there is a defect in binding of the inducer to the product of the lacl gene C. glucose and lactose are both readily available in the growth medium D. the operator has mutated so it can no longer bind repressor E. none of the above
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.
