Met-Val-Ser-Thr-Lys Val-le-Trp-Thr–Leu-Met-lle Leu-Phe-Asn-Glu-Ser-Arg The sequences of the smaller peptides produced by chymotryp- sin digestion were as follows: Asn-Glu-Ser-Arg-Val-lle-Trp Thr-Leu-Met-Ile Met-Val-Ser–Thr–Lys-Leu–Phe Deduce the sequence of the original peptide.
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 sample of a peptide of unknown sequence
was treated with trypsin; another sample of the same peptide was
treated with chymotrypsin. The sequences (N-terminal to C-terminal)
of the smaller peptides produced by trypsin digestion were as follows:
