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.

Description
Test your understanding of the central dogma of molecular biology with this quiz. Explore the flow of genetic information from DNA to RNA to protein, and learn about exceptions to this fundamental theory. Delve into the concept of prions, infectious proteins that challenge the traditional flow of genetic information.
