The virus has been in the limelight in the past two years, which is unforgettable to everyone.
All major media across the country broadcast it all day, and all major virus experts made a detailed science popularization about the virus to the people all over the country.
This invisible and intangible micro organism has had an unimaginable huge impact on the macro social economy, and also let everyone remember its five major characteristics.
1.Popular science about viruses
Viruses have a unique mode of reproduction and do not have a complete enzyme system. The host is the processing factory. An insect is the processing factory for insect viruses, and a person is the processing factory for human viruses. For example, people needs to wear masks to reduce COVID-19 infection.
2.The volume of the virus is very small, measured in nanometers (nm), so it cannot be seen or touched.
For example, the size of the cockroach virus that can infect cockroaches is only 20nm, which is the same size as the human hepatitis B virus. It looks like a small ball under the electron microscope with 100000 times magnification.
3. No resistance
For example, the size of the cockroach virus that can infect cockroaches is only 20nm, which is the same size as the human hepatitis B virus. It looks like a small ball under the electron microscope with 100000 times magnification.
4.For example, the size of the cockroach virus that can infect cockroaches is only 20nm, which is the same size as the human hepatitis B virus. It looks like a small ball under the electron microscope with 100000 times magnification.
5.Viruses only contain one type of nucleic acid, DNA or RNA. Not both. For example, the nucleic acid material of COVID-19 is RNA, which is more prone to mutation.
