How do activators facilitate transcription? Activator (inactive) Activator- binding site RNA polymerase Promoter Transcription normally off. RNA polymerase cannot bind to the promoter unless the activator is bound to the activator-binding site, but the activator is in an inactive form. Inducer Activator (active) Inducer helps turn transcription on. Transcription Inducer binds to the activator and changes its shape, allowing the activator to bind to the site. RNA polymerase can then bind to the promoter and initiate transcription.

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.
