Question

20 different ___ ___ link together to form chains. A protein is composed of one or more of these ___ chains which are twisted and folded into a particular shape.

Answer 1

Answer:Amino acid, polypeptide/polynucleotide chains

Explanation: Amino acids are usually the building blocks of protein hence,every protein is made up of one or more amino acids.

A protein consist of one or more polypeptide chain that is folded into a helix shape. This shape is to prevent the easy degradation of the components that makes up the polypeptide because it is water loving and can easy degrade.

Answer 2

Answer: Amino acids; peptide

Step-by-step explanation:

20 different AMINO ACIDS link together to form chains. A protein is composed of one or more of these PEPTIDE chains which are twisted and folded into a particular shape.

There exists 20 amino acids capable of forming protein in the Human body. At least two amino acids are joined together by a peptide bond to form polypeptide chains that are then held together by hydrogen bonds in twisted alpha helical structures to form proteins.
