Fascinating! (Disclaimer: I am not a biologist or gene scientist.) This is sort of like the anti-matter concept in Physics, but applied to DNA and other living structures. Again, fascinating! This leads to another question, which is does light have chirality too? What about other waves in the electromagnetic spectrum? Does chirality affect a plant's ability to process sunlight? Is there a reverse-chirality version of sunlight? Oh, the questions and the possibilities! Great link for Hacker News!
