If a mutation occurred in a control element sequence associated with a particular gene, which of the following would be a likely consequence of this? A. This mutation is not likely to affect the expression of the associated gene, because RNA polymerase does not bind to control elements. B. This will likely affect the expression of the associated gene because it will loosen the coiling of chromatin at this site. C. The expression of the associated gene will be affected because this change will result in a nonsense mutation. D. This mutation is not likely to affect the expression of the associated gene, since control elements are noncoding sequences. E. The associated gene's expression would likely be affected, since this mutation would change the ability of at least one transcription factor to bind.

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.
