Novel coronavirus could be a hybrid of bat and pangolin viruses: study

The video explores the origins of COVID-19, suggesting it may be a hybrid of bat and pangolin viruses. It highlights the genetic similarities between the bat virus RaTG13 and SARS-CoV-2, noting a 96.3% RNA similarity, but points out the absence of spike protein parts in the bat virus. The video also discusses the potential recombination of bat and pangolin viruses, which could lead to the formation of SARS-CoV-2, explaining how recombination occurs when two similar viruses infect the same cell, resulting in a new pathogen.

What is the closest genetic relative to SARS-CoV-2 according to the research?

• MERS-CoV

• SARS-CoV-1

• Pangolin virus from China

• Bat virus Rat G. 13

Which virus lacks the spike protein parts used by SARS-CoV-2 for human infection?

• Pangolin virus

• SARS-CoV-1

• MERS-CoV

• Bat virus Rat G. 13

What feature of the pangolin virus closely matches SARS-CoV-2?

• Receptor binding domains

• Cell wall composition

• RNA sequence

• Spike protein structure

How can recombination occur between two viruses?

• When they are frozen

• When they are exposed to sunlight

• When they infect the same cell

• When they infect different cells

What happens to the molecules of distinct viruses during recombination?

• They become inactive

• They remain unchanged

• They are reshuffled into a new pathogen

• They are destroyed
