Bio-Tech: Biogenesis
Biogenesis is tissue engineering (above) taken to the point where biological molecules can be assembled into a viable organism. Nanomachines lay down a polymer or carbon composite scaffolding and assemble bone, muscle, nerves, and other tissues on this framework. The cells are controlled by artificial chromosomes, designed to produce the proteins and enzymes needed by the resulting organism. Often the designers will take shortcuts, using clusters of nanofactories to produce required proteins that couldn't be coded into the genes, either because of lack of understanding or development time. The result is that the organism is a mixture of biological parts and artificial components.
Biogenetic organisms come in all sizes, from insect-sized up to building-sized or larger. Since construction throughout the organism is simultaneous, they all take around the same time to build: four to six weeks. Larger organisms require more nano and raw materials, however, and thus are proportionately more expensive. Biogenesis can be used to create a wide variety of organisms, including copies of animals, designer lifeforms such as the skullcat, and biogadgets.
Any biogenetic organism will have Unusual Biochemistry.
