NEW CORONAVIRUS VARIANTS - EXPLAINED SIMPLY

This video explains coronavirus variants, mutations, PCR tests in simple terms, so that you can make more sense of media reports and the changing restrictions to our daily lives. You will also learn some cool molecular biology! The video is intended for a wide audience.
The video will cover four areas of science so you will be able to follow the facts behind the global pandemic:
• The main features of the SARS-CoV2 virus, which causes the COVID19 pandemic.
• How the main PCR test for COVID19 works, as unexpected results in these tests are linked to the rapid spread of a new variant of COVID19 in the United Kingdom.
• How mutations arise and how they can affect the behaviour of the virus.
• The two mutations found in rapidly spreading coronavirus variants that are causing concern and a new wave of strict lockdown restrictions
