1. Nucleic acids

2. Nucleic acids What are they? What do they do? What is it made of?
DNA and RNA
What do they do?
What is it made of?
Nucleotides

3. nucleotides
Three parts:

4. Sugar and phosphate

5. Bases
A,G,C, and T are found in DNA
A,G,C, and U are found in RNA

6. Base Pairing
Held together with hydrogen bonds.

7. DNA untwisted

8. Model building CTACGGATG 18 Black T’s = deoxyribose sugar
9 White sticks = hydrogen bonds
18 White tubes = phosphate
5 Red tubes = guanine
4 Green tubes = adenine
4 Blue tubes = thymine
5 Black tubes = cytosine
