29. What is riboflavin, and how is it related to energy-carrying molecules?
30. How is information stored in DNA? How many bases in DNA correspond to every amino acid in a protein?
31. In what sense are the two strands in DNA complementary to one another? How is this complementation achieved? What structural features in the side groups of the two DNA strands make incorrect matching difficult (although not impossible) ?
32. What is the three-dimensional structure of DNA? How does this structure follow from the complementarity of the strands? How does this structure protect the genetic information?
33. In what sense is DNA the "archival material" of a cell? To what molecule is the information in the DNA initially transcribed? What is done with this information thereafter?
