What is the PCR process, what else can it be used for? And: How safe is the test anyway?
Summary
[edit]| Description |
English: PCR stands for “Polymerase Chain Reaction”. It is a method to specifically track down and reproduce genetic material. In principle similar to a copier. In order for the copier to know what to duplicate, it needs a suitable template - a unique DNA sequence of the virus. Such typical locations in the genome of Sars-CoV-2 are known. With the help of a tool: a so-called “primer” that was synthesized in advance to search for precisely these points, this sequence is tracked down in the sample.
Deutsch: PCR steht für “Polymerase Chain Reaction”. Es ist eine Methode um Erbsubstanz gezielt aufzuspüren und zu vervielfältigen. Im Prinzip ähnlich wie ein Kopierer. Damit der Kopierer weiß, was er vervielfältigen soll braucht er eine geeignete Vorlage – eine unverwechselbare DNA-Sequenz des Virus. Solche typischen Stellen im Erbgut von Sars-CoV-2 sind bekannt. Mit Hilfe eines Werkzeugs: einem sogenannten „Primer“ der vorab für die Suche nach genau diesen Stellen synthetisiert wurde, wird diese Sequenz in der Probe aufgespürt. |
