Each protein is a molecule made up of different combinations of 20 types of smaller, simpler amino acids. Protein molecules are long chains of amino acids that are folded into a three-dimensional ...
How can just four nitrogenous bases--adenine, cytosine, guanine, and uracil--possibly code for all 20 amino acids? Thus, early researchers quickly determined that the smallest combination of As ...
The other two are fat and carbohydrates. Protein consists of long chains of amino acids. There are 20 amino acids. The specific order of amino acids determines the structure and function of each ...
