Sometimes a transcription factor within the cytoplasm can act as an intracellular receptor for a ligand. When activated, such transcription factors can alter gene expression by preventing chaperone proteins from entering the nucleus. changing shape after binding their ligands and entering the nucleus. attaching ligands to their extracellular binding sites. activating effector proteins. binding to the nuclear membrane.

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.
