So there is this thing called mirror DNA or L-DNA. However, the idea that mirror DNA is inherently dangerous is more speculative. Here’s why:
Biological Systems Can't Read It – Natural enzymes, proteins, and cellular machinery are evolved to work with right-handed DNA. Left-handed DNA (or mirror-DNA) would be biologically inert because living organisms wouldn’t have the right molecular "tools" to interact with it.
Potential Applications – Scientists have considered using L-DNA for medical and nanotechnology applications because it’s resistant to normal enzymes that degrade DNA. It could be useful for ultra-stable drugs or molecular computing.
Hypothetical Dangers – Some science fiction-like theories suggest that if an organism could evolve or be engineered to use mirror-DNA, it might be resistant to antibiotics or immune responses. However, creating such an organism would be an enormous challenge since all cellular machinery would need to be mirrored, not just the DNA.
Did the theory you read suggest a specific danger, like bioweapons or self-replicating synthetic life?
Theoretically there can be a species of pseudo humans with L-DNA that eat humans
