How come we have 20 amino acids and they make thousands of proteins please give me reasons
Kryger [21]

Answer:

The human body uses just 21 amino acids to make all the proteins it needs to function and grow. Because amino acids can be arranged in many different combinations, it's possible for your body to make thousands of different kinds of proteins from just the same 21 amino acids.
