1. Macromolecules Three: Nucleic Acids Biology Standard 1d

2. Org. Compounds: Nucleic Acids Large, complex molecules made of C, O, H, N, P. 2 types are RNA, ribonucleic acid and DNA, deoxyribonucleic acid.

3. DNA

4. RNA What are the Differences? RNA VS DNA??

5. Nucleic Acid Structure Each large compound is formed from monomers called nucleotides. Each nucleotide contains: 1 Phosphate Group 1 Sugar 1 Nitrogen Base

6. Phospha te PO 4 Makes up a part of the DNA/RNA backbone

7. Sugar In DNA, sugar is deoxyribose In RNA, sugar is ribose Binds to Nitrogen Base Is in backbone of DNA/RNA

8. DNA Nitrogen Bases Adenine Thymine Guanine Cytosine

9. DNA Base Pairing Rules A only binds with T C only binds with G H bonds hold Nitrogen bases together

10. RNA Nitrogen Bases Adenine Cytosine Guanine Uracil NO… T!
