Molecular biology is a discipline within the life sciences that investigates biological processes at the level of molecules, primarily nucleic acids and proteins. It focuses on the mechanisms of DNA replication, repair, recombination, transcription, and RNA processing, as well as translation and post-translational modification of proteins. Molecular biology integrates concepts and methods from biochemistry, genetics, and cell biology, employing techniques such as cloning, PCR, sequencing, gene editing, and transcriptomic and proteomic profiling. It underpins contemporary research in areas including gene regulation, signal transduction, developmental biology, pathogen–host interactions, and the molecular basis of disease.
Proteins are critical to life—and to industry. There are countless proteins that could be engineered to treat and even cure serious diseases and cellular dysfunctions. Industrial applications are similarly promising, with ...
