Where did the red and gray coronavirus image come from and why does it look like that?
We’ve all seen it, the red and white sphere image above that represents the coronavirus.
But what does this symbol really mean?
First and foremost – it’s an image from the CDC. It was created to represent the virus, but, in reality, this is what the coronavirus looks like under an electron microscope.
Getting back to the CDC graphic – the little red nodules are proteins, and the virus is the genetic material in a protein casing.
That’s what the gray is – genetic material.
Coronavirus is an RNA virus.
RNA is a messenger, carrying instructions from DNA for controlling the merging of proteins.
Viruses reproduce by injecting their genetic material into a host cell.
That forces the host cell to make copies of the virus, rather than the cell performing its normal function. Thus the reason viruses are so easily spread.
