Molecular Biology

Molecular Biology in the MCAT roughly consists of fully understanding four important mechanisms:

1. DNA Replcation - How does the cell copy its genetic material?
2. Transcription - How is DNA converted to RNA
3. Translation - How is the RNA converted to synthesize protein. After all it are the proteins which do all the work.
4. Regulation - How do we regulate this process.

This section serves to answer the central dogma of Molecular Biology:

How is DNA converted to RNA which is converted to Protein and how this is regulated?

Understanding this is very important for the MCAT, as many experimental data that are presented require a firm understanding of these basic facts.
