Study Notes
Nucleic Acids
- Two types: DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid)
Nucleotide Structure
- Building block of nucleic acids is a nucleotide
- Three components: pentose sugar, nitrogenous base, and phosphate group
Sugars in Nucleic Acids
- DNA: Deoxyribose sugar
- RNA: Ribose sugar
Nitrogenous Bases
- Purines: Adenine and Guanine
- Pyrimidines: Cytosine, Thymine (DNA), and Uracil (RNA)
DNA vs. RNA Nitrogenous Bases
- Key difference: DNA contains Thymine, while RNA contains Uracil instead of Thymine.
