1. If the mammalian genetic code were a four letter code, then it would have the potential to encode...   216 amino acids   128 amino acids   64 amino acids   256 amino acids   Hint Half-n-half Clue   2. The triplet base sequence of tRNA nucleotides that is complementary to an mRNA codon (for a particular amino acid) is called :   a transposon   a cistron   a retroposon   an anticodon   Half-n-half Clue   3. 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 :   translocation   dislocation   RNA processing   elongation   Half-n-half Clue   4. Every polypeptide chain formed in translation starts with the amino acid :   methionine   lysine   alanine   serine   Half-n-half Clue   5. 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 lysosome   a polysome   a centrosome   a peroxisome   Half-n-half Clue   6. A sequence of about 5 to 20 bases seperating one stop codon from the next start codon in a polycistronic prokaryotic mRNA molecule is called :   a poly-A-tail   a transposon   a spacer   a Shine Dalgarno sequence   Half-n-half Clue   7. 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
