Question

the model shows an overview of protein folding. order the steps to make a protein with more than one polypeptide chain. first several polypeptide chains assemble to form the folded protein amino acids assemble into a polypeptide chain alpha helices and beta sheets fold into a three - dimensional structure parts of a polypeptide chain fold into shapes like an alpha helix last

Explanation:

Protein folding starts with amino acids assembling into a polypeptide chain. Then parts of the chain fold into shapes like an alpha - helix. After that, alpha helices and beta sheets fold into a three - dimensional structure. Finally, several polypeptide chains assemble to form the folded protein.

Answer:

1. amino acids assemble into a polypeptide chain
2. parts of a polypeptide chain fold into shapes like an alpha helix
3. alpha helices and beta sheets fold into a three - dimensional structure
4. several polypeptide chains assemble to form the folded protein
