1. Nucleic Acids and ATP

2. Nucleic Acids Named because they were first found in the nucleus of cells VERY VERY BIG Contain C, H, O, N and P

3. Nucleotides The Building Block of Nucleic Acids

4. Nucleotides Continues 3 parts: – Phosphate Group – Nitrogenous Base – Sugar Deoxyribose in DNA Ribose in RNA

5. Phosphate Group PO 4

6. Nitrogenous Base Adenine Cytosine Guanine Thymine Uracil

7. Genes About 1000 rungs of DNA make a single gene

8. Structure DNA – double helix – Contains T and not U RNA – Single Stranded – Contains U and not T – mRNA, tRNA and rRNA

9. ATP Adenosine TriPhosphate Transfers energy from energy releasing reactions to energy-requiring reactions that maintain cellular activities

10. Structure 3 phosphate groups attached to an adenosine molecule

11. Energy Transferring Reaction Via hydrolysis, the last phosphate group is removed and releases energy Produces ADP – adenosine Diphosphate
