PAGE 1: Complete the table: a. isolated “nuclein”; analyzed and found it is an acid that is rich in phosphorous b. Griffith c. Mimicked Griffith’s work with bacteria & mice & found that DNA is the transforming factor (molecule of heredity) d. Confirmed that DNA is the transforming factor (experiment used phage and bacteria) Label-match: 6. deoxyribose (B) 7. phosphate group (G) 8. purine (C) 9. pyrimidine (A) 10. purine (E) 11. pyrimidine (D) 12. nucleotide (F) PAGE 2: General DNA questions 22. DNA is a simple molecule common to every organism. Because its letters can vary so much in their sequence, an enormous array of proteins can be made (resulting in a vast array of organismal diversity) 23. All the nucleotides on one side are “upside down” compared to the other side. Thus, the sugars, phosphate groups, and N-bases all run opposite on the two strands.
