Section 1 (pgs 193-195)
1.) Using the picture to the right, describe
Griffith’s experiment and the results.
2.) How did Avery use Griffith’s 4th experiment on the mice to discover what substance is the hereditary
material?
3.) Describe the two experiments and the results of the Hershey-Chase Experiment.
1.)
2.)
Section 2 (pgs 196-199)
4.) Who were the individuals who proposed a model for DNA and took an X-ray diffraction picture of
DNA, showing its double helix structure?
5.) _________________ are subunits of DNA, which repeat using three main parts …
1.) ______________________ - a five carbon sugar molecule.
2.) _________________ ___________ - Phosphorous atom bonded to 4 oxygen atoms.
3.) _________________ ___________ - Nitrogen and carbon atoms.
6.) Two Nitrogenous bases are the _______________ , which have a double carbon ring and the
______________________, which have a single carbon ring.
7.) What are the two Purines and the two Pyrimidines and which ones are involved in base pairing?
Name: ____________________________
8.) What would be the complementary DNA strand to the following DNA strand?
*G G GT A C C T A A A T C C T G A C
Section 3 (pgs 200-202)
9.) What does Helicase do during DNA replication? (and what Y-shaped region is formed?)
10.)What does DNA polymerase do during DNA replication? (how does this go with the semi-conservative
model of replication?)
11.)Draw a simple picture of DNA replication. (label the two DNA strands, DNA polymerase, Helicase, and
the replication fork)
12.)What could cause mutations?
Section 4 (pgs 204-210)

15.)Using the following DNA strand, what would be the RNA strand made by transcription? [*note- do not
forget the Uracil (U) is in RNA instead of Thymine (T)]
*A G C T T A A C C G C A A G C G G
16.)A _____________ is a 3 nucleotide sequence in mRNA that encodes an amino acid.

sequences (remember to start and stop at the correct codons) (*hint – convert DNA into RNA and the
RNA into amino acids using the above chart)
