1.Which of the following is not an example of a protein with quaternary structure? a. Calmodulin is a Ca2+-binding protein which is formed by two identical subunits. b. Hemoglobin in adult humans has the composition αα2ββ2. c. The photosynthetic enzyme Rubisco is composed of 8 L subunits and 8 S subunits. d. Myoglobin, an oxygen-binding protein in muscle, consists of a single subunit. e. South American rattlesnake toxin (crotoxin) is a phospholipase A enzyme with two different subunits. 2.Complete the sentence with the best option provided below. The secondary structures of a protein are the a. chemical modifications of amino acid side chains. b. temporary, unstable protein folding conformations. c. regular, repeated folds present in a lowest energy conformation. d. interactions between polar amino acid side chains.
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.
