Transcriptional regulators are proteins that bind to promoters (at the 5’ flanking regions of genes) to regulate their transcription. Assume that a particular transcription regulator normally promotes transcription of gene X that codes for a membrane transport protein. If a mutation makes this transcription regulator nonfunctional, would the resulting phenotype be similar to a deleterious mutation in the membrane transporter itself? Why or why not?
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.
