1. Synthesis of proteins can take place quickly by multiple ribosomes being able to attach themselves to one mRNA chain. An mRNA chain with multiple ribosomes is called :   a centrosome   a lysosome   a polysome   a peroxisome   Hint Half-n-half Clue   2. Some tRNAs can recognize more than one codon because there is a relaxation of the complementation rule of base pairing between the anticodon and codon in the third position (of the codon sequence). This relaxation is called :   the Levene's Hypothesis   Sutton-Boveri Hypothesis   the Monkey-Man Hypothesis   the Wobble Hypothesis   Half-n-half Clue   3. Most amino acids are encoded by more than one codon except tryptophan and :   lysine   glycine   methionine   leucine   Half-n-half Clue   4. The difference in the products translated from a tricistronic mRNA molecule by the ribosomes of prokaryotes and eukaryotes is that :   the prokaryotic ribosome translates only one cistron while the eukaryotic ribosome translates all cistrons.   the eukaryotic ribosome translates only one cistron while the prokaryotic ribosome translates all cistrons.   the eukaryotic ribosome will produce one polyprotein instead of three smaller proteins.   None of the above.   Half-n-half Clue   5. The movement of peptidyl tRNA from the A site to the P site (of the larger ribosomal subunit) and the movement of mRNA in relation to the ribosome is called :   dislocation   elongation   translocation   RNA processing   Half-n-half Clue   6. The enzyme that forms a peptide bond between adjacent amino acids in the ribosome during translation is called :   peptidyl transferase   Deiodinase   Phospholipase   Diastase   Half-n-half Clue   7. Which of the following statements is correct ?   Methionine is found at the N-terminus of nearly all newly synthesised eukaryotic proteins.   Each mRNA molecule is usually translated into, hundreds of copies of a single polypeptide chain.   In prokaryotes, both transcription and translation take place in the same part of the nucleus.   All of the above.   Half-n-half Clue
