Pt1420 Unit 2 Study Guide
1. A:The three types of a nucleotide are Deoxyribose sugar, Phosphate, and a Nitrogen Containing base.
B: Deoxyribose Sugar is found in Nucleotides.
C: The nucleotide component that contains Nitrogen is the base.
D: The four types of nitrogen bases are Adenine, Thymine, Guanine, and Cytosine.
2. A: .......
B: The parts of the oligonucleotide that make up the rungs of the ladder in the ladder model are the nitrogen bases.
C: The parts of the nucleotide that make up the sides of the ladder in the ladder model are the phosphates and the Deoxyribose Sugars.
D: The bottom and top of the ladder in the ladder model are anti-parallel.

4. The nucleotide that contains Adenine must be attached to a Thymine. …show more content…
5.
There must be 2 hydrogen bonds in between Adenine and Thymine.
6. The nucleotide that contains a Cytosine must be connectwed with a Guanine.
7. There must be 3 hydrogen bonds in between Cytosine and Guanine.
8. Adenine and Thymine only connect with each other using 2 hydrogen bonds. Guanine and Cytosine only connect with each other using 3 hydrogen bonds.

10. The Double Helix model of DNA looks like two rods twisting together.

12.A: The type of biological molecule in the DNA helicase is an enzyme.
B: The role of the DNA helicase in the replication of DNA is it separates the hydrogen bonds.
13. The rule that is used to join the free nucleotides to the exposed bases of the DNA is the Complementary base rule.
14. The DNA replication of DNA is called semi-conservative replication because half of the original DNA is kept and the other half is used to replicate.
