Gene Cloning vs. PCR: What's the Difference?
Edited by Janet White || By Harlon Moss || Updated on October 29, 2023
Gene cloning involves creating copies of a gene within a host organism; PCR (Polymerase Chain Reaction) amplifies DNA segments rapidly in a test tube.
Key Differences
Gene cloning entails inserting a specific gene into a host organism, leading to the production of multiple copies of that gene. PCR, on the other hand, is a laboratory technique used to amplify a specific DNA segment without the need for a host.
The process of gene cloning often involves the use of vectors, such as plasmids, to transfer and replicate the gene of interest in a host organism. PCR utilizes primers, DNA polymerase, and thermal cycling to exponentially amplify targeted DNA sequences.
Gene cloning results in the production of multiple copies of a gene within a living organism, which can then express the protein coded by the gene. PCR allows for rapid amplification of DNA in vitro, often used for diagnostic or research purposes.
While gene cloning is a method for producing multiple copies of a gene for further study or use in protein production, PCR is primarily used for analyzing DNA, such as in forensic science or genetic testing.
The applications of gene cloning extend to producing pharmaceuticals and genetically modified organisms. In contrast, PCR has a wide range of applications including DNA sequencing, diagnosis of diseases, and detection of pathogens.
