Interesting Veritasium YouTube on PCR tests and how they came to be

[gmax137]

I found this to be very interesting - as someone who never really paid attention to biology. I have heard of PCR testing during the CoVid days, but I didn't know what "polymerase" is, or what "chain reaction" had to do with the test.

Veritaseum is always a good source of interesting stuff.

Veritaseum has a checkered history with some of his videos. One should always second source his stuff. His videos on speed of light measurement and electricity in a wire are particularly atrocious. He's also been known to misquote Einstein.
