Test your basic knowledge |

First Aid: Biochemistry Molecular

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. 1P blocked by chloramphenicaol and macrolide






2. VItamin C






3. Aminoacyl - tRNA binds to A site 2) peptidyltransferase catalyzes peptide bond formation transfers growing polypeptie to amino acid in A site 3) ribosome advances 3 nucleotides toward the 3 prime end of RNA moving peptiydyl RNA to P site






4. Antigout - acts on mts






5. (A - G) 2 rings Pure As Gold






6. Condensed - transciptionally inactive HC- Highly condensed






7. CCA AT 3 PRIME END






8. RNA polymerase I makes rRNA - RNA pol II makes mRNA - RNA pol III makes tRNA
