Step 1: Introduction
Deoxyribonucleic acid also known as DNA, is a molecule that houses the genetic instructions required for all known living things to grow, develop, operate, and reproduce. Many viruses also include DNA. Adenine (A), thymine (T), cytosine (C), and guanine (G) are the four nucleotide bases that make up the lengthy, double-helix structure of DNA. A always pairs with T, and C always pairs with G, making these bases complementary pairings.

A polypeptide was treated with trypsin to generate a series of fragments of the following sequences: Gly-Gly-Ile-Arg Ser-Phe-Leu-Gly Trp-Ala-Ala-Pro-Lys Ala-Glu-Glu-Gly-Leu-Arg And the same polypeptide was treated with chymotrypsin to generate the following fragments: Leu-Gly Ala-Glu-Glu-Gly-Leu-Arg-Trp Ala-Ala-Pro-Lys-Gly-Gly-Ile-Arg-Ser-Phe Assemble the protein sequence.arrow_forward
