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.
Differentiate between gene expression in
heterochromatic and euchromatic regions
Gene expression involves the flow of information to form the target protein. It is the process that uses the coded genetic information in the genome of the organism to synthesize target proteins. Gene expression involves two main steps namely transcription and translation. Transcription involves the synthesis of single stranded mRNA using DNA as template and translation involves the synthesis of amino acids using the mRNA triplet codon.
