Once your Serums are full of DNA (they will land in the output slot on the right) you are ready to inoculate your first Larva.
Insert your full Serum Array into the Inoculator, along with a Larva. Fill the Inoculated with Bacteria Vector. This is another long process. It takes around an hour per gene, but once it’s done, you will have a new Larva. The last step of this process is to now Incubate the Larva.
