They invented a new term to obfuscate facts about food energy-dependent RNA-mediated DNA repair.

CCR5 encodes a protein that some common strains of HIV use to infect immune cells. This gene interacts among microRNA-mediated networks of genes. That makes editing a threat to humanity if it promotes virulence in biophysically constrained HERVs.

Ask someone who knows how energy-dependent cell type differentiation occurs before editing genes that biophysically constrain viral latency. The facts about RNA-mediated cell type differentiation are too difficult for amateurs to understand.
