Introduction to Biochemistry
Nucleic Acid Structure
DNA and RNA form the genetic blueprint and signaling molecules necessary for protein synthesis.
Composition
- DNA uses deoxyribose, phosphate, and nitrogenous bases.
- RNA uses ribose and uracil instead of thymine.
- Base pairing: A-T and C-G in DNA; A-U and C-G in RNA.
Medical Implications
- Chemotherapy agents often target DNA replication cycles.
- Genetic testing identifies mutations leading to hereditary diseases.
