DNA Logic Design: Computing with DNA - Hardcoverby Hafiz MD Hasan Babu (Author) A DNA computer is a collection of specially selected DNA strands, which when encoded into specific combinations are then subjected to bio molecular manipulation in order to solve computational problems. Rather than storing information in the 1s and 0s of the binary number system, it is now stored in the form of the bases adenine (A), thymine (T), cytosine (C) and guanine (G). These bases can be arranged into short
