SEQAD is a computer programme which automatically assembles from nucleotides the building blocks of DNA and RNA. Gene sequences could in theory, in a petri dish, build their own outer biological skins to form a cell, given the right conditions. These artificial cells could be given specific and intricate functions within the human body.
