1. Prokaryotes use 70S ribosomes which consist of :   a (small) 30S and a (large) 50S subunit   a (small) 40S and a (large) 60S subunit   a (small) 10S and a (large) 60S subunit   a (small) 40S and a (large) 30S subunit   Hint Half-n-half Clue   2. Most amino acids are encoded by more than one codon except tryptophan and :   leucine   methionine   glycine   lysine   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. tRNA molecules are linked to their respective amino acids by enzymes called :   Ornithine decarboxylases   aminoacyl-tRNA synthetases   beta-galactosidases   phenylalanine hydroxylases   Half-n-half Clue   5. 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   6. The process of translating mRNA into protein occurs...   inside the Peroxisomes   at the ribosomes   within the nucleus   inside the Lysosomes   Half-n-half Clue   7. Every polypeptide chain formed in translation starts with the amino acid :   serine   methionine   alanine   lysine   Half-n-half Clue
