1. 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.   Hint Half-n-half Clue   2. Most amino acids are encoded by more than one codon except tryptophan and :   methionine   leucine   glycine   lysine   Half-n-half Clue   3. The triplet base sequence of tRNA nucleotides that is complementary to an mRNA codon (for a particular amino acid) is called :   a cistron   a retroposon   a transposon   an anticodon   Half-n-half Clue   4. In prokaryotic mRNA, a particular base sequence (AGGAGGU) exists near the AUG start codon. This sequence which is sometimes referred to as the ribosome binding site is known as :   a Shine Dalgarno sequence   a trailer sequence   a Kozak's consensus sequence   a promoter sequence   Half-n-half Clue   5. If the mammalian genetic code were a four letter code, then it would have the potential to encode...   64 amino acids   128 amino acids   216 amino acids   256 amino acids   Half-n-half Clue   6. The base inosine is usually found in :   mRNA   hnRNA   rRNA   tRNA   Half-n-half Clue   7. Which of the following pairs of codons encode the same protein ?   UAA and UAC   GUA and GUG   UAG and UAC   AUG and AUC   Half-n-half Clue
