Study Notes
Nucleic Acids Basics
- Two main classes of nucleic acids: DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid).
- RNA nucleotides contain ribose sugar, while DNA nucleotides contain deoxyribose sugar.
Role of Nucleic Acids
- Nucleic acids are essential for the storage and transmission of genetic information.
- They play a crucial role in directing protein synthesis, acting as templates for synthesizing proteins.
Base Composition
- Both RNA and DNA contain the bases adenine (A), cytosine (C), and guanine (G).
- Thymine (T) is specific to DNA, while RNA includes uracil (U) in place of thymine.
RNA Structure and Properties
- Single-stranded RNA can fold back on itself into structures resembling hairpins due to complementary base pairing.
- RNA is capable of existing in double-stranded formations under the right conditions without requiring additional complementary sequences.
Watson & Crick Model
- The Watson & Crick model provides a framework for understanding the structural classification of B-DNA.
- This model explains the helical structure and base-pairing of nucleic acids, essential for DNA and RNA functionality.
