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 is nuclear DNA ?
The genetic material of a eukaryotic cell is DNA (deoxyribonucleic acid). It contains genes that encode information related to metabolic activities, cell growth, and proliferation among others. The genes are transcribed into messenger RNA (ribonucleic acid) that is later translated into the cytoplasm to produce protein molecules. The protein molecules are the ultimate molecules that directly take part in different cellular activities.
