     Protein Review Answers:

     1. B - DNA is replicated first, then it is transcribed into mRNA, which is then used to direct protein synthesis. The protein is then expressed as the physical trait.

     2. D - mRNA must bind to the small ribosomal subunit before initiation with tRNA - Methionine can occur.

     3. C - The mRNA strand, composed of codons, directs the synthesis of the protein.

    4. E - All of the events are necessary for the polypeptide chain to continue its elongation.

     5. D - Translation continues until termination, when the ribosome encounters the STOP codon on the mRNA.

     6. C - Bacteria are NOT too simplistic for controlling their protein synthesis. Jacob and Manod demonstrated this with their 1961 experiment.

     7. TRUE - Lactose is a common inducer of protein synthesis in prokaryotes. Again, Jacob and Manod demonstrated this in their famous experiment of 1961.

     8. FALSE - Methionine, the first amino acid to be added to every protein, is added at the P site during initiation.

     9. FALSE - It is the ribosome that moves along the mRNA during translocation.

     10. FALSE - Metamorphosis in insects cannot occur until the production of juvenile hormone is stopped.
