Question
Chapter 21, Problem 6IQ
Summary Introduction
To explain: About the evolution of lysozyme and α lactalbumin for which the genes for both proteins are found in mammals but not in birds.
Introduction: Amino acids are the building blocks of the body. They are synthesized by specific sequence of nitrogenous bases during translation. These amino acids combine to code for specific proteins that are involved in various biochemical processes.
