These molecular biology PDF books explain how DNA, RNA, and proteins work together inside every cell. You'll see how genes are copied, read, and turned into the molecules that keep us alive.
The collection runs from full open textbooks to short guides on the central dogma. It also includes lab manuals with real PCR and cloning protocols, plus a starter shelf on bioinformatics.
Some books run over 700 pages, others take an afternoon. Every book opens in your browser and downloads for free.

Molecular Biology Textbooks
Start here if you want the full course in molecular biology, from DNA structure to gene regulation. These open textbooks and course notes explain each idea through the experiments that proved it.
A complete open textbook that walks you from DNA structure and replication to transcription, translation, and gene regulation. Every chapter explains the experiments behind each discovery, so you learn how scientists figured it out.
A graduate-level classic that teaches molecular genetics through the experiments that proved each idea. Covers DNA replication, transcription, gene regulation, and recombination with a focus on reasoning from first principles.
An open textbook that joins cell biology and molecular biology, from DNA and gene expression to membranes, signaling, and the cell cycle. Each chapter links key ideas to the research that uncovered them.
Lecture notes built for medical laboratory students, starting with classical genetics and moving to DNA, gene expression, and molecular diagnostic techniques. Each chapter opens with learning objectives and closes with review questions.
A clear primer on genes, DNA, and the tools of genetic engineering, from cloning to transformation. It closes with how biotechnology is used in crops, livestock, and fisheries.
A short course module that covers the essentials in five units: genes and chromosomes, nucleic acids, DNA replication and transcription, the genetic code, and protein synthesis. Tutor-marked questions close each unit.
Replication, transcription, and translation are the three steps of the central dogma of molecular biology. These books zoom in on each one, from how DNA is copied to how genes are switched on and off.
A full course on how genetic information is copied, read, and controlled, with detailed chapters on DNA replication, transcription, RNA processing, translation, and gene regulation. Problem sets help you check what you learned.
A short illustrated guide to how DNA becomes RNA and RNA becomes protein. Its color diagrams make replication, transcription, and translation easy to picture in one sitting.
A collection of research reviews on how cells start, pace, and finish copying their DNA. It covers replication origins, licensing, fork protection, and the checkpoints that keep the genome stable.
Research reviews on what happens when DNA replication stalls or breaks down, and how helicases and repair pathways rescue the process. A solid reference for anyone studying genome stability.
A collection of studies on how genes are switched on and off, from RNA polymerase and transcription factors to chromatin and non-coding RNA. It also shows how faulty regulation leads to disease.
Theory clicks faster once you run your first gel. These molecular biology manuals walk you through DNA extraction, PCR, restriction digests, and cloning, step by step.
A hands-on manual with step-by-step protocols for PCR, ligation, bacterial transformation, plasmid preps, RNA extraction, real-time PCR, and western blots. It even includes a nanopore sequencing lab.
The theory behind the bench, explained clearly. These notes cover DNA purification, gel electrophoresis, vectors and cloning, restriction enzymes, protein gels, and PCR troubleshooting.
The complete lab manual of an applied molecular biology course, built around a real genetic screen in yeast. You follow each step, from DNA digests and transformation to plasmid recovery and sequencing.
A practical manual organized around a research project on gene regulation. Short chapters cover primer design, PCR, restriction digests, ligation, transformation, and DNA and RNA extraction.
A full semester of lab work built around one project: amplify a gene by PCR, clone it, express the protein, and purify it. Each chapter adds background, protocols, and expected results.
Modern molecular biology produces more DNA sequences than anyone can read by hand. These books teach you to align, search, and analyze genomes with a computer, starting from zero.
A beginner course from the National Cancer Institute that takes you from your first Unix commands to a full RNA-Seq analysis and pathway interpretation. No prior coding experience needed.
Learn to work with DNA and RNA sequences using Python, Biopython, and the command line. Covers file formats, sequence alignment, genome browsers, and next-generation sequencing data.
A friendly introduction to analyzing DNA and protein sequences in R. You retrieve sequences from online databases, compute GC content, align sequences, and build phylogenetic trees.
The official guide to Biopython, packed with ready-to-use code for reading sequence files, running BLAST, querying NCBI databases, and working with protein structures and phylogenies.
The open textbook of an MIT course on the algorithms behind genomics. Covers sequence alignment, hidden Markov models, gene finding, regulatory networks, and molecular evolution.
