1. 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 promoter sequence   a trailer sequence   a Shine Dalgarno sequence   a Kozak's consensus sequence   Hint Half-n-half Clue   2. 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 Shine Dalgarno sequence   a spacer   a poly-A-tail   a transposon   Half-n-half Clue   3. 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   4. Prokaryotes use 70S ribosomes which consist of :   a (small) 10S and a (large) 60S subunit   a (small) 30S and a (large) 50S subunit   a (small) 40S and a (large) 60S subunit   a (small) 40S and a (large) 30S subunit   Half-n-half Clue   5. 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 Monkey-Man Hypothesis   Sutton-Boveri Hypothesis   the Wobble Hypothesis   the Levene's Hypothesis   Half-n-half Clue   6. 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   7. The triplet base sequence in DNA that is translated into a stop codon, whose corresponding tRNA anticodon, is AUU is given by :   TAA   CGG   ATT   GCC   Half-n-half Clue
