Study Notes
Molecular Biology Fundamentals
- The central dogma of molecular biology outlines the flow of genetic information from DNA to proteins.
- Creutzfeldt-Jakob disease is a rare neurologic disorder caused by infectious prion proteins.
DNA Structure
- The building blocks of DNA are nucleotides, consisting of a sugar molecule, a phosphate group, and one of four nitrogenous bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
Contributions to Molecular Biology
- In 1958, Francis Crick developed the sequence hypothesis, which proposes that the sequence of nucleotides in DNA determines the sequence of amino acids in proteins.
Genetic Information
- The complete genetic information that defines the structure and function of an organism is known as its genome.
