What are proteins? How are they structured? What’s the difference between a protein in a human and the same protein in a lizard? Ask Mary Anne Clark these questions and she is likely to respond with an earful of music.
Clark is a biologist at Texas Wesleyan University in Fort Worth, and she’s part of a growing field of science educators who use so-called protein music to help illustrate the basic structure of the building blocks of life.
All living things are made up of proteins. Each protein is a string of amino acids. There are 20 different amino acids, and each protein can consist of dozens to thousands of them.
