Nucleic acids Carbohydrates Lipids Proteins Nucleic acids

Functions of nucleic acids / nucleotides Building blocks of chromosomes –1. –2. Energy carriers –1. Capture reducing power –1. –2.

Nucleic acid structure DNA and RNA have a couple important differences –The sugar –The choice of nucleotide bases –Know the difference between DNA and RNA!

DNA = ___________________________ RNA = ___________________________ The nucleic acid has three components: 1._____________ 2._____________ 3._____________

The purines are: The pyrimidines are:

Dehydration to form the nucleotide from its component units

Dehydration reactions to link nucleotide units to form nucleic acids Always name nucleic acids from 5’ to 3’ !!!

ATP / ADP = adenosine triphosphate / adenosine diphosphate

NADH = nicotinamide adenine dinucleotide; NADPH = nicotinamide adenine dinucleotide phosphate

Nomenclature considerations The building block unit nucleic acids is the __________ The individual component pyrimidines and purines are called: The names change when they are incorporated into the nucleotide structure:

The names are abbreviated in a couple ways: –Three letter abbreviations: (for DNA, for RNA) –One letter abbreviations:
