1. | The positional information of amino acids in a protein is called the primary structure. |
2. | Alpha helix is a secondary structure and beta pleated sheet is a tertiary structure of a protein. |
3. | Tertiary structure is absolutely necessary for the many biological activities of proteins. |
4. | Quaternary structures are seen in proteins made of more than one polypeptide chain. |
