Biochemistry, Molecular Biology, and Genetics

At the heart of modern medicine lies the molecular language that dictates cellular function, metabolism, and heredity. This textbook integrates core biochemical pathways, gene expression regulation, and genetic variation with clinical implications across specialties. It explains enzymology, metabolic networks, nucleic-acid structure and function, and principles of genomics and proteomics in clear, clinically relevant terms. Laboratory techniques — PCR, sequencing, Western blot, and CRISPR basics — are described alongside examples of diagnostic and therapeutic applications. Ethical, counseling, and translational aspects of genetics (carrier screening, pharmacogenomics) are addressed to bridge bench and bedside. Ideal for medical students, laboratory scientists, and clinicians seeking a compact molecular foundation.
