What is a virus?

Viral RNA Chopper and Destroyer
Specially evolved RNAs and proteins detect strands of invading viral RNA and chop them up.
Another set of RNAs and proteins pick up some of the chopped-up viral RNA from Step 1. You can think of them as setting up security checkpoints near a cell’s ribosome, where translation occurs. These molecular border guards compare incoming messenger RNA (mRNA) that comes from either the virus or the host cell against their small pieces of the virus’s genetic code. Anything that matches codes for something that the virus is trying to make, so they slice it up before it gets through.
Two-Shape RNA Switch
Step 2: Design a riboswitch that can detect Molecule X by binding to it and switching shape.
Step 3: Tweak your RNA switch so that when it switches to its second shape, that shape activates “cell death.” Cell death is a natural process that your body already uses to eliminate sick cells.
