Molecular biology is simply the study of biological molecules and their interactions. It is also a collection of techniques developed since the field of genesis which have enabled scientists to learn about molecular processes. In this way it has both complemented and improved biochemistry and genetics as methods that began before its advent. One notable technique which has revolutionized the field is the polymerase chain reaction (PCR), which was developed in 1983. PCR is a reaction which amplifies small quantities of DNA, and it is used in many applications across scientific disciplines.
The central dogma of molecular biology describes the process in which DNA is transcribed into RNA, which is translated into protein.
Molecular biology plays a critical role in the understanding of structures, functions, and internal controls within individual cells, all of which can be used to efficiently target new drugs, diagnose disease, and better understand cell physiology. Some clinical research and medical therapies arising from molecular biology are covered under gene therapy whereas the use of molecular biology or molecular cell biology in medicine is now referred to as molecular medicine.
