Hershey/Chase –

Rosalin Franklin –

Watson/Crick –

2.     Which macromolecule was a good candidate for the molecule of the gene, but proved to NOT carry any genetic information?  Why was it a good candidate?

3.     How is DNA like  a book?

World’s Easiest Practice Quiz – Discovery of DNA, structure of DNA

1.     What phenomenon did Griffith discover?

2.     What moved from the dead lethal bacteria to the living harmless bacteria?

3.     Avery determined what the molecule of the gene is by …

4.     Hershey and Chase __________ Avery’s results.

5.     What is the molecule of the gene (the genetic chemical)?

6.     What molecule was in contention for, but we now know is NOT, the molecule of the gene?

7.     DNA must do what 3 things?

8.     Chargaff’s Rule says A & ____ , and G & ____ are always in equal amounts.

9.     A nucleotide consists of a nitrogenous base, a phosphate group, and ____________.
