The full name of PCR is the polymerase chain reaction. It is a very powerful technology that can replicate DNA in a very simple but efficient way. It can be regarded as a special DNA replication outside the organism.
A clean bench (also called a laminar flow bench or laminar flow workstation) is a piece of equipment designed to create a micro-environment that meets industry standards for particulate control. Clean benches range in size from compact tabletop versions to larger cabinets. Many manufacturing environments, such as semiconductor, pharmaceutical, medical device, food, aerospace and nanotechnology production, require that products be kept free of particulate contamination.
Polymerase Chain Reaction (PCR) is a process where millions of copies of DNA are amplified from a single copy, or low copy number template. This reaction is fundamental to almost all applications requiring high copy number of starting material and is used in all laboratories working with DNA and RNA.
