In the image, arginine 79 is shown to be important for the stabilisation of the quaternary protein complex. What will happen if the arginine is substituted for a glutamine? Arg 79 a. The mutation is more hydrophobic and will make the interaction tighter. b. There will be no change. c. The mutation will allow more water molecules to bind and disrupt the interaction causing the complex to break. d. The negative charge of the R group will repel against the negative charge opposite causing the complex to break. e. Some hydrogen bonding will be possible and the quaternary complex will be weaker but still form.

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.
