1. How many amino acids are encoded by the following mRNA sequence : UAUCAUCCACUUGGUUGA ?   4   7   6   5   Hint Half-n-half Clue   2. The base inosine is usually found in :   mRNA   rRNA   tRNA   hnRNA   Half-n-half Clue   3. Which of the following pairs of codons encode the same protein ?   GUA and GUG   AUG and AUC   UAA and UAC   UAG and UAC   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 Kozak's consensus sequence   a trailer sequence   a Shine Dalgarno sequence   a promoter sequence   Half-n-half Clue   5. Every polypeptide chain formed in translation starts with the amino acid :   serine   alanine   lysine   methionine   Half-n-half Clue   6. 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 :   RNA processing   dislocation   translocation   elongation   Half-n-half Clue   7. 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
