If a mutation deletes the promoter in a eukrayotic gene, which of the following most accurately describes its consequence? A. There will be no mRNA or polypeptide made. B. The mRNA will be made but no polypeptide is made. C. The mRNA will not be processed properly. D. Nothing will happen. It is a silent 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.

mRNA means messenger RNA. mRNA forms from the template DNA strand. The template DNA strand is used as a template to transcribe the mRNA. mRNA act as a template for the synthesis of protein or polypeptide chain that occur in the cytoplasm of the cell.
