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.
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.
