Digestion of a peptide with trypsin generates two smaller peptide products: methionine-glycine and tyrosine-lysine. Digestion of the same peptide with cyanogen bromide (CNBr) also generates two smaller peptide products: glycine and tyrosine-lysine-methionine. What is the sequence of the original peptide? a.) tyrosine-lysine-methionine-glycine b.) methionine-glycine-tyrosine-lysine c.) glycine-tyrosine-lysine-methionine d.) tyrosine-glycine-methionine-lysine
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.

a.) tyrosine-lysine-methionine-glycine
pepsin is a serine protease that cleaves the bond present in the C-terminal of amino acids Lysine and Arginine. cyanogen bromide(CNBr) is an inorganic compound that is often used to digest proteins. it cleaves the bond at the C-terminal of methionine.
