====Basic chemicals====
These are the basic chemicals for virus mutation. You can either add them directly to a virus to obtain a random level symptom, or mix them with other ingredients to get [[Guide_to_chemistry#Virology_Recipes|advanced chemicals]], that will give you a specific level symptom.

* '''[[Virus Food]]''': You can make virus food with Water and Milk. Virology lab has its own Virus Food Dispenser. Mixing this with a disease will give that disease a symptom of level 1 to 2.
* '''[[Unstable Mutagen]]''': You can use mutagen to mutate your disease and give it a symptom of level 2 to 4. Virology starts with a 30u bottle of mutagen.
* '''[[Plasma|Liquid Plasma]]''': Plasma can be used to mutate your disease to give it a symptom of level 4 to 6. Plasma in liquid form is generally in very limited supply, unless mining and chemistry cooperates with you. Virology starts with a 30u bottle of liquid plasma, and in some station layouts with extra plasma bars.
