Corona virus already had new type evolusive mutant to world. That must be natural selective outcome. DAN composition structure is based on four letters with ATGC. However, this time's corona virus peril made it clear that mutant birth must rely on some kind of DNA transcription errors. And ultimately our human's species with fundamental feature and distinctive nature must have had been fixed with these transcsriptive accidents in accumlating and very coincidental natural selective occurence made now our holding reality as DNA condition.
Then, if we truly could know the mechanism of DNA transcription's periodic mechanism and external factor in relevance and synergism or so, possibly we could discover DNA's four letters' incomplete nature which we could never have had explicated, of course it is just my one thinking experiment. 
However, these four letters' some incomplete nature might have driven RNA's ever believed central dogma's incomplition resulting, if the supposion was correct, necessarily DNA's four letters' universality must face another explication by us. And if we could explicate our species birth enigma with various data of species' bifurcation at systematized mechanism in long periorical order, we would have our virus pandemic horror overcome.

These are just my one imagination, but at least our future vision, only dualism must not be so omonipotent, only that thing could be pursuasive in terms of now our standing crisis. Necessarily these presumption must be connected with transposon's unidentified mechanism beyond DNA four letters. In other words, at nature world, more big scaled long periodical mutation and transcriptive error driving unindentified natural selective mechanism or system could have been present potentially. Messenger RNA's driving personnel as macro factor would be mechanized at natural selective unidentified regulation.

For explicating, at least biochemistry, pale-ontology, and physics or geology must have cooperation, together for figuring out our earth's ecosystematic impact and mutual relevance.

There, let us go back to very practical our social spot.
Our first set index beforehand of our job mission must be partially occupied with detachment around past thing, with regretful emotion and introspective mind to it.
Our job mission's premise revised index and objective target and reformative method's application.
In other words, it must mean revisional intention to past's serial process realized our achievement, and second index must be the outputted result caused from our application to newly updated index.
And we must get partially, established and accomplished targeted parts, but simultaneously we must get partially never fulfilled objected, aimed things. This gap driving our assessing to our job means our learnt and acquiered knowledgeable and emprical understanding to our following truth.

Anytime when we resume our job, we must use certain thing and uncertain thing. Former means our learnt truth and latter means our trial at try and error, that must mean experiment.

This truth could be exampled or adopted either to mathematics' axiom and theorem.

Our known uncertain number means (impossible) imaginary numbers and irrational numbers. Former means impossibility to dsiplay on coordinate axes as positioning, or kind of presentation's inabilty for us, necessarily that nature could be relevant with our mind's understanding to words with languages' structure, with our emotional brain driving realization to our mind.
Latter means imposibility to identify the precise position on coordinate axes, but it must be the issue of measuring for us, as precisional degree, equal to numerical formulation, then really we practically arbitrarily cut so micro precision, and e.g. we build the archetectual structures. Hence, necessarily it has similarity to identify just now on time system.
In terms of precision measuring, it must be connected with Uncertainty principle by Heisenberg.

Additionally notice to next chance as Part4; Next will be about odd numbers and multiple correlations in mathematics, because it must be seen so integral for displaying act on coordinate axes, in other words, at this consideration, we must have our essential understan ding to our own world and our own interaction to this universe as nature world.
