Question 2 What primarily determines the specific chemical character of a particular amino acid? 0 A. The Y group. O B. The amino (NH3+) group. O C. The carboxyl (CO0-) group 0 D. The R group O E. The methyl (CH3) group Question 3 Hydrophobic and ionic interactions between the R groups of amino acids occur at which level of protein structure? O A. quatermary O B.tertiary C. secondary O D. primary Question 4 are proteins that bind to polypeptides and facilitate their proper folding. O A. Codons ? B Enzymes O C. Ribosomes O D. Chaperones O E. Ribozymes Question 5 Which of the following is a site on the ribosome where uncharged tRNAs bind? OA.A ?C.E O D. W Question 7 Translocation of the ribosome occurs during O A initiation O B. elongation C. termination D. transcription

Explanation / Answer

Question 2. Options D R group provide the functional specificity to the protein.

Question 3. Option B Tertiary level of protein structure. R group forms hydrogen, ionic bonding,dipole-dipole interactions, and London dispersion forces (non-covalent bonds)

Question 4. Option D Chaperones is correct.

Question 5.  Option C the uncharged tRNA (from which the amino acid is removed) bind to the E site of the ribosome during the protein translation process.

Question 7. Option B translocation of ribosome occurs during the elongation phase of translation of protein synthesis.
