4. A polypeptide has the following amino acid sequence: Met-Ser-Pro-Arg-Leu-Glu-Gly In the mutant below, indicate the type of mutation that occurred in the DNA and the phenotypic effect of the mutation Met-Ser-Pro-Asp-Trp-Arg-Asp-Lys a. Single base substitution/nonsense mutation b. Insertion/missense mutation c. Deletion/ frameshift mutation d. Deletion/missense mutation e. Single base substitution/frameshift mutation A non template strand on bacterial DNA has the following base sequence. What amino acid sequence will be encoded by this sequence? 5. 5-ATG ATA CTA AGG CCC-3 a. Tyr Tyr Asp Ser Gly b. c. d. e. Met Ile Leu Arg Pro Met Leu Ile Asp Pro Tyr Val His Stop Met Ile Ile Arg Pro The following mRNA sequence is encoded by a gene Q. 5'--3' What would be the consequence of adding an extra G (guanine) base to the gene Q sequence immediately after the start codon? a. There was no consequence. b. A frameshift occurred which altered the identity of the amino acids following the initiator 6. methionine, but not the length of protein Q. c. A frameshift occurred which altered the identity of the amino acids following the initiator methionine in protein Q AND shortened it to only eight amino acids. d. Splicing was altered. e. A longer protein.

1. an enzyme is considered a(n) because it speeds up a chemical reaction without being used up.2. in a catalyzed reaction, a reactant is often called a(n) . an enzyme is specific because the shape of its matches only particular reactants.4. an enzyme speeds up reactions by lowering the . the between an active site and its substrate often strains bonds and the reaction proceed.6. a( , which is often a vitamin, binds to an enzyme and plays a role in catalysis.7. high temperatures or changes in ph can an enzyme, causing it to lose its shape and biological activity.
