I thought it is ironic that viruses help us to breathe and keep us alive yet they kill us. Viruses kill most of the bacteria in the ocean that produce toxic gases like Ammonia and Methane. If all the viruses magically disappeared, the air would very quickly become toxic and breathing would be impossible.
It is also ironic that the Covid19 virus can't move, breathe, or consume anything yet it spread to every part of the earth. It doesn't even have DNA, it uses RNA. RNA is like one unzipped half of the DNA molecule and uses the same code except the Thymine is replaced by Uracil, not sure why though. Our cells make RNA when it reads the DNA. The Covid19 virus is just RNA code.
Covid19 viruses can't move, they are only alive when they are inside the cell so all the movement is done by the infected person. It is spread by our bodies and can't move, when the sun shines, the UV rays destroys most of the virus particles in the air so it spreads better in the winter when the days are shorter.
The virus particles can't even get into the cells on their own. The ends of their spike proteins look like sugar molecules so the cell pulls the virus in because it thinks it is sugar.
