Abstract: In view of the defect of the traditional computernonreversible computation. A fresh theory is proposed which combines the realization rationales of the three kinds of computers with structural characteristics to devise a new logic. It refers to the central dogma by thinking of the mock noncoded chains of DNA as information units. Thus, it will correspondingly form a quite differen t series of logic rules and be able to calculate reversibly. Accordingly, we call it computing-reversibly logic.

Key words: reversible, nanocomputer, DNAcomputer, noncoded chains, central dogma
