1. 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 :   Sutton-Boveri Hypothesis   the Wobble Hypothesis   the Levene's Hypothesis   the Monkey-Man Hypothesis   Hint Half-n-half Clue   2. Every polypeptide chain formed in translation starts with the amino acid :   lysine   methionine   alanine   serine   Half-n-half Clue   3. 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 Kozak's consensus sequence   a promoter sequence   a trailer sequence   Half-n-half Clue   4. Prokaryotes use 70S ribosomes which consist of :   a (small) 30S and a (large) 50S subunit   a (small) 10S and a (large) 60S subunit   a (small) 40S and a (large) 60S subunit   a (small) 40S and a (large) 30S subunit   Half-n-half Clue   5. Which of the following is not a stop codon ?   GUA   UGA   UAG   UAA   Half-n-half Clue   6. 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   7. Most amino acids are encoded by more than one codon except tryptophan and :   leucine   lysine   glycine   methionine   Half-n-half Clue   FREE PREVIEW: Last 10 Questions not a part of the free preview.
