Nucleic Acids and ATP
Nucleic Acids Named because they were first found in the nucleus of cells VERY VERY BIG Contain C, H, O, N and P
Nucleotides The Building Block of Nucleic Acids
Nucleotides Continues 3 parts: – Phosphate Group – Nitrogenous Base – Sugar Deoxyribose in DNA Ribose in RNA
Phosphate Group PO 4
Nitrogenous Base Adenine Cytosine Guanine Thymine Uracil
Genes About 1000 rungs of DNA make a single gene
Structure DNA – double helix – Contains T and not U RNA – Single Stranded – Contains U and not T – mRNA, tRNA and rRNA
ATP Adenosine TriPhosphate Transfers energy from energy releasing reactions to energy-requiring reactions that maintain cellular activities
Structure 3 phosphate groups attached to an adenosine molecule
Energy Transferring Reaction Via hydrolysis, the last phosphate group is removed and releases energy Produces ADP – adenosine Diphosphate
