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.
In a cell that produces only one type of protein, which of the following statements about the relationship between hnRNA and mRNA is TRUE? O Heterogeneous nuclear RNA is always larger than mRNA. O Heterogeneous nuclear RNA is always smaller than mRNA. O Heterogeneous nuclear RNA and mRNA are typically the same size. O Heterogeneous nuclear RNA is always the same molecule as mRNA. There is no consistent relationship between the size of the two molecules.
