1. The triplet base sequence in DNA that is translated into a stop codon, whose corresponding tRNA anticodon, is AUU is given by :   GCC   TAA   ATT   CGG   Hint Half-n-half Clue   2. 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   Half-n-half Clue   3. Prokaryotes use 70S ribosomes which consist of :   a (small) 40S and a (large) 30S subunit   a (small) 40S and a (large) 60S subunit   a (small) 10S and a (large) 60S subunit   a (small) 30S and a (large) 50S subunit   Half-n-half Clue   4. How many amino acids are encoded by the following mRNA sequence : UAUCAUCCACUUGGUUGA ?   5   4   7   6   Half-n-half Clue   5. tRNA molecules are linked to their respective amino acids by enzymes called :   beta-galactosidases   Ornithine decarboxylases   aminoacyl-tRNA synthetases   phenylalanine hydroxylases   Half-n-half Clue   6. The process of translating mRNA into protein occurs...   inside the Peroxisomes   within the nucleus   inside the Lysosomes   at the ribosomes   Half-n-half Clue   7. 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 poly-A-tail   a transposon   a spacer   a Shine Dalgarno sequence   Half-n-half Clue
