24. How can only 4 Nitrogen bases code for 20 amino acids?
25. In relation to number 24, how can only 20 amino acids produce the huge variety of proteins in the body?
26. What is the first codon in every protein made and what is the corresponding amino acid?
27. Why is each amino acid usually coded for by several different codons; wouldn't one codon be sufficient?
28. Why are mutations so devastating to proteins?
29. What is the difference between a codon, an anticodon and a triplet?
THE GENETIC CODE
30. The union of what "players" in translation constitutes proper initiation?
STEP I OF PROTEIN SYNTHESIS: INITIATION
31. How are amino acids arranged in proper order on an mRNA strand?
32. How are peptide bonds between amino acids formed (give the chemical diagram AND the facilitating enzyme in translation).
33. What are the "A" and "P" sites? Are they fixed points on the mRNA?
STEP II IN PROTEIN SYNTHESIS: ELONGATION
34. What signals the end of translation?
35. What happens to the following at the end of translation: tRNAs, mRNA, the ribosome, the protein?
STEP III IN PROTEIN SYNTHESIS: TERMINATION
