BIO 189 - Final: Modules 4-7
1. Nucleotide: Monomers of nucleic acids (DNA
and RNA)
2. Chargaff's rules: A=T and C=G
3. Hershey and Chase: Scientists who discovered that DNA was the
genetic material (not protein) by using bacteriophage viruses
4. Bacteriophage: A type of virus that infects bacteria
Used by Hershey and Chase in their experiments that showed that
DNA is the genetic material
5. Rosalind Franklin: Scientist who took pictures of DNA using x-ray
crystallography, which helped discover the double helix shape of
DNA
6. Watson and Crick: Team of scientists that built the first accurate
model of the double helix shape of DNA
7. Double helix: The shape of DNA. Two long strands wrapped
around each other.
,8. Hydrogen bond: Weak attractions that hold together the two strands of DNA in a double
helix
9. Base pair: A pair of complementary nitrogenous bases in a
DNA molecule
10. DNA: Nucleic acid polymer that acts as the genetic
material for ALL life forms
11. RNA: Nucleic acid polymer that is a temporary copy of a
specific segment of DNA
12. Gene: A segment of DNA on a chromosome that codes
for a specific product (usually a protein)
13. Three chemical components of a nucleotide: 1)
Nitrogenous base
, 2) Five-carbon sugar
3) Phosphates
14. Nitrogenous base: The chemical component of a nucleotide that makes each
nucleotide different from the others
15. Nucleotides in DNA: Adenine, Thymine, Guanine, Cytosine
16. Nucleotides in RNA: Adenine, Uracil, Guanine, Cytosine
