How Does PCR Work?
In recent years, the term "PCR" has become a buzzword in the scientific community, media, and even mainstream conversations. This trend is largely attributed to its widespread use in COVID-19 testing and research. However, PCR, or Polymerase Chain Reaction, has been a reliable tool in molecular biology for decades. This article aims to provide a comprehensive overview of what PCR is, how it works, and its real-world applications beyond the COVID-19 pandemic.
No, PCR was first described in the 1980s by Kary Mullis. However, its applications have expanded significantly in recent years.
The COVID-19 pandemic has brought PCR to the forefront of public attention. With millions of tests performed worldwide, PCR has proven to be an efficient and accurate method for detecting the SARS-CoV-2 virus. However, PCR's significance extends beyond this pandemic. In the US, PCR has been used in various fields, such as:
Reality: PCR was first described in the 1980s, but its applications have expanded in recent years.
Myth: PCR is a New Technique
PCR is used to amplify specific DNA sequences, whereas DNA sequencing determines the order of the nucleotide bases in a DNA molecule. While PCR can be used in conjunction with DNA sequencing, they are distinct techniques.
