Understand that proteins are made up of building blocks called amino acids.
Recognize that there are 20 standard amino acids that are used by cells to synthesize proteins.
These 20 amino acids are encoded by the universal genetic code found in DNA.
Each amino acid has a specific side chain, which gives it unique properties and functions in protein structure.
Remember that while there are more than 20 amino acids in nature, only these 20 are directly coded for by the genetic code and are used in the synthesis of proteins in all living organisms.
