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.
The base pairing of DNA and RNA differ slightly in their nucleotide bases. DNA uses the bases Adenine (A), Thymine (T), Cytosine (C), and Uracil (U) while RNA in their nucleotide bases has Adenine (A), Uracil (U), Cytosine (C) and Guanine (G). three bases are the same but the one base is different that is RNA use uracil instead of thymine (in DNA).
