Choose the statement that correctly characterizes regulated and/or constitutive gene expression. Regulated expression refers to gene expression that is either on or off, depending on the physiological or metabolic status of the cell. Constitutive expression refers to gene expression that is either on or off, depending on the physiological or metabolic status of the cell. Constitutive expression refers to gene expression that is always repressed in response to the absence of required nutrients other metabolic molecules. Regulated expression refers to gene expression that is always on, regardless of the metabolic or physiological conditions in the cell. Regulated and constitutive expression are terms used to describe gene expression in prokaryotes only.

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.
