1. If the mammalian genetic code were a four letter code, then it would have the potential to encode...   216 amino acids   64 amino acids   256 amino acids   128 amino acids   Hint Half-n-half Clue   2. 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   3. 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 peroxisome   a centrosome   a lysosome   a polysome   Half-n-half Clue   4. Which of the following is not a stop codon ?   GUA   UAG   UAA   UGA   Half-n-half Clue   5. How many amino acids are encoded by the following mRNA sequence : UAUCAUCCACUUGGUUGA ?   4   5   7   6   Half-n-half Clue   6. tRNA molecules are linked to their respective amino acids by enzymes called :   Ornithine decarboxylases   phenylalanine hydroxylases   aminoacyl-tRNA synthetases   beta-galactosidases   Half-n-half Clue   7. 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 :   dislocation   translocation   elongation   RNA processing   Half-n-half Clue
