One mystery about #Covid19 are the two genetic insertions highlighted in the red box, that started the rumors of bioengineering. Chinese scientists learned in 2015, just *two insertions from *bats on a #coronavirus will change #MERS & #SARS from harmless, into deadly pathogens.

In the graphic, you’ll see that there are two unknown receptors, one from each RNA stand. Research being done by the Chinese scientist at the Univ. of Minnesota also employed a change to the receptors in order to turn on the virus’s infectious ability.

#COVID19 is altered in such a way that the protein at the end of the spikes is rotated (in gold). This is how it binds to the cell wall where it could, before. (Note: the 90 degree rotation in the graphic is for viewers purposes and not the rotated protein, itself.)

Dr Li, also, published finds on the same type of dual mutation process in 2005, using #SARS instead of #MERS. Another Chinese paper describes the use of a synthetic #HIV-based proteins applied to a SARS bat virus’s spikes, to either increase or decrease ACE2 receptor efficiency.
