Study Notes
Nucleic Acids
- Nucleic acids are complex molecules containing carbon, hydrogen, oxygen, nitrogen, and phosphorus.
- They are responsible for storing and transmitting genetic information.
- DNA (deoxyribonucleic acid) is the genetic material of all living things.
- DNA is a double helix, made of two strands of nucleotides.
- RNA (ribonucleic acid) is a single-stranded molecule involved in protein synthesis.
- RNA is transcribed from DNA and then translated into proteins.
Biomolecules
- The four main categories of biomolecules are carbohydrates, lipids, proteins, and nucleic acids.
- Each category contains diverse molecules with distinct structures and functions.
- Understanding biomolecules helps us understand how they contribute to life processes.
