Which of the following amino acid or types of amino acids are are rarely found in beta sheets? a. Polar charged amino acids  b. Polar uncharged amino acids  c. Non polar amino acids  D. Glycine

All 20 amino acids found in human proteins have a common structure that includes:   A. An amino group (-NH2)   B. A carboxyl group (-COOH)   C. An R group   D. A and B   E. A, B, and C

Answer the following multiple choice questions, and pick from the following a, b, c, d

Which of the following describes the most likely outcome of a mutation that causes a sin- gle amino acid to be removed from a protein subunit? A It will affect the primary, secondary, and tertiary structures of the protein. B с D It will affect the secondary and tertiary structures of the protein but not the primary structure. There will be no observable effect on the structure of the protein. It will change the primary structure of the protein without affecting other structures in the protein.

How would adding acid to a non-buffered solution be most likely to affect protein structure? Select one: a. Adding acid would disrupt the primary structure of the protein b. Adding acid would cause the protein to become a lipid c. Adding acid would cause the protein to become a carbohydrate d. Adding acid would disrupt the secondary and tertiary structure of the protein
