The problems with mirror- and anti-organisms.

The anti-universe and anti-Earths are interesting ideas. The terms "Anti-Earth" and "anti-biospheres" don't only mean the antimatter universe or antimatter planets. There is also one little-known meaning about those things. That "Anti-Earth" means the planet or biosphere where everything acts oppositely. 

In that anti-Earth's biosphere proteins, and DNA are the mirrors of Earth proteins and DNA. That causes an interesting model: how do those hypothetical species with different or mirror molecular structures act? The idea is that: if our cells use right-handed molecules and proteins the "mirror-worlds" lifeform uses the left-handed proteins and handles everything oppositely. 

Researchers say that anti-bacteria can cause problems. But how far can we go into genetic research, that researches things, like mirror genomes? Can the "anti- or mirror-human" be possible? 

"Mirror life presents serious dangers, primarily due to its potential to interact unpredictably with the natural world. Without natural checks like predators or antibiotics, mirror organisms could replicate uncontrollably, creating risks that scientists are only beginning to understand.

The mirror organisms used in the research how mirror genetics act against natural organisms. And that brings the frightening scenario in front of our eyes. That thing is the anti-human. The anti-human would have the DNA in the mirror form in their cells. Some people think that this kind of person cannot survive. 

The reason for that is in protein handlers. Those protein handlers would handle only mirror proteins, and that causes the death of that organism. But what if we would not be so lucky? What if that creature can turn proteins into the opposite or mirror form? 

What would happen if we put the  DNA in the opposite direction into the cells? Many people say that this thing causes immediate death. That is a misunderstanding. The DNA molecule is a linear code. That means: the cell must read those base pairs in the way that they encode the mRNA that shuts down the cell. The base pairs come oppositely into the cell, and the result would be the same as we drive program code in the opposite direction. That causes mutations and many other things. 

Then we can think about "mirror-organisms". Those mirror-organisms are normal bacteria whose DNA is turned into its mirror. Those things cause grey hair for ecosystem researchers. They have no idea how those organisms behave. Do they treat their mirror bacteria or natural bacteria as "enemies"?

The mirror organisms cause an idea that is one of the most dangerous in the world. What would the anti-human look like? Of course, the "anti-human" has a phenotype of humans. But their genotype can be the opposite, or mirror version of humans. The mirror-human, or anti-human is one of the most frightening models of mirror-organisms. 

What if those mirror humans have cells that can turn their amino acids and proteins around? If that creature has bacteria or other cells that can turn proteins around, that person uses the same food that we eat. But what kind of thing could that version be?
