Mr. Mullis’s PCR test does not test for a specific virus. Yes, it amplifies RNA/DNA fragments, but it cannot tell you what the amplified fragments of a random sample belong to. There are hundreds of different kinds of coronaviruses in the world, they range from colds to flu's; the PCR amplification process has no idea what has been amplified. It cannot specifically differentiate convid-19 from any other coronavirus. The elusive convid-19 was never isolated, purified, verified, and visualized according to a scientific method called Koch’s postulate; it is not possible to distinguish it from any other virus. The test is not valid in testing for the alleged convid-19 virus on any level. Mr. Mullis won the Nobel Prize for inventing the PCR amplification test. He died just four months before the alleged covid-19 virus was declared. Had he lived; he would have pulled the plug on using the PCR test to detect a specific virus, thus making it impossible to lockdown the world and destroying global economies and lives.
