Select the answer that correctly expresses a valid comparison between transcriptional regulation in eukaryotic cell and prokaryotic cells. OA. The glucocorticoid response element is most closely compared to the lac repressor, since these both work in trans to suppress expression of the target gene. O B. The glucocorticoid receptor is most directly compared to the lac repressor protein, since both prevent expression of their target genes but are removed from their binding site after being bound by allolactose. There are no valid comparisons between transcriptional regulation in prokaryotes and eukaryotes. OC. O The glucocorticoid receptor is most closely compared to the lac operon operator sequence, since these both function in cis to regulate their associated gene. O E. The glucocorticoid response element is most closely compared to the CAP site, since binding of regulatory proteins to these sequences leads to an increase in transcription of the regulated gene.

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.
