Bio computer

Bio computers use biologically derived molecules — such as DNA and proteins — to perform digital or real computations. This is made possible by nanobiotechnology. They can be biochemical, biomechanical or bioelectronic. All biological organisms have the ability to self-replicate and self-assemble into functional components. The economical benefit of biocomputers lies in this potential. They use transcriptors which are transistor-like devices composed of DNA and RNA rather than a semiconducting material such as silicon.

This is early technology eventually used to make bioships.

Bio-neural gel packs from Star Trek had fibers capable of making billions of connections, thus generating a sophisticated and responsive computing architecture. This allowed computers to "think" in very similar ways to living organisms; by using "fuzzy logic", they could effectively operate by making a "best guess" answer to complex questions rather than working through all possible calculations.
