1. Bacteriophage proteins with 35S-labeled proteins and 32P- labeled DNA are used to infect unlabeled bacteria. The bacteriophage replicate their DNA within the host cells, produce new protein coats, and package the replicated DNA in the new protein coats, all using the host’s machinery. When the bacteria lyse, releasing viral progeny into the medium, the viral progeny. A. contain both 35S labeled proteins and 32P labeled DNA B. contain 35S labeled proteins but not 32P labeled DNA C. contain 32P labeled DNA but not 35S labeled proteins D. contain 35S labeled proteins but not 32P labeled DNA E. contain no label in their DNA or in their proteins 2. Which of the following is true of both DNA and RNA synthesis? A. The newly synthesized nucleic acid remains paired to the template nucleic acid. B. The polymerase involved catalyzes equally well the addition of incoming nucleotides to either the 5’ or 3’ end of the growing nucleic acid. C. The nucleic acid is synthesized discontinuously and the pieces then joined together. D. Where the parental strand has an A, U hydrogen bonds to it in the newly synthesized strand. E. The parental strand and the complementary strand whose synthesis it specifies are antiparallel 3. Proteins that are synthesized in their entirety on free ribosomes in the cytoplasm include: A. chloroplast proteins that are specified by nuclear DNA B. mitochondrial proteins that are specified by mitochondrial DNA C. lysosomal enzymes D. signal peptidase E. the Na+K+ ATPase 4. If you were to remove the ER-retention signal from a protein that normally resides in the ER lumen, where do you expect the protein will ultimately end up? A.
