It covers current cell and molecular biology techniques and principles with a clinical focus what a physician needs to know to understand, diagnose, and treat human disease. Molecular biology is often taught within various courses such as biochemistry, microbiology, and histology; thus, a consolidated review book in molecular biology is especially helpful in preparing for the USMLE Step 1. This edition has been streamlined to remove content covered in other High-Yield books such as histopathology and microbiology. Images have been placed closer to the appropriate text. New figures include DNA melting curve and flow cytometry.
