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 results in the alteration of amino acid sequences during polypeptide formation in protein synthesis?
-
A defective polypeptide may arise because of a change in its amino acid sequence
-
Despite the change in amino acid sequence, the polypeptide formed will always be functional and will never cause a disease.
-
The cell will have no other choice but to revert the faulty polypeptide into amino acids to undo its work.
-
The nucleus, by means of its powerful enzymes, will eventually destroy the damaged protein so that it will not wreak havoc in the cell.
