1. 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 centrosome   a peroxisome   a polysome   a lysosome   Hint Half-n-half Clue   2. The process of translating mRNA into protein occurs...   inside the Lysosomes   inside the Peroxisomes   within the nucleus   at the ribosomes   Half-n-half Clue   3. tRNA molecules are linked to their respective amino acids by enzymes called :   Ornithine decarboxylases   beta-galactosidases   aminoacyl-tRNA synthetases   phenylalanine hydroxylases   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 promoter sequence   a Shine Dalgarno sequence   a Kozak's consensus sequence   a trailer sequence   Half-n-half Clue   5. 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   6. 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   7. Every polypeptide chain formed in translation starts with the amino acid :   serine   alanine   methionine   lysine   Half-n-half Clue
