Chapter 6, Problem 9P

Interpretation Introduction

Interpretation:

The three amino acids whose replacement never yields a positive score in the Blosum-62 matrix are to be identified. The features of these residues that contribute to the given observation are to be stated.

Concept introduction:

The organic compounds that contain amine $\left({\text{-NH}}_{\text{2}}\right)$ and carboxyl $\left(\text{-COOH}\right)$ functional groups with a side chain $\left(\text{-R}\right)$ are known as amino acids. Proteins are the biomolecules which are composed of the long chain of amino acid residues.
