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.

What part of a gene is important in initiating transcription?
Promoter region
Exons
Introns
Structural gene
RNA processing plays a role in the regulation of gene expression. RNA processing is essential for generating functional mRNA molecules and regulating gene expression, and defects in RNA processing can lead to a wide range of diseases, including cancer and neurodegenerative disorders.
