  Abstract &
  Background 		Abstract Biomolecular computing, including DNA computing, RNA computing and protein computing, is a kind of computing mode of information processing whose "data" is biomolecule. In addition, the biomolecular computing mode using PNA molecule as "data" was presented. This paper does not discuss PNA computing, RNA computing and protein computing because their research results are less. Clearly, it is a foundation problem to know well the structure and character of the "data" (that is DNA molecules) in DNA computing. So, this paper mainly discusses the structure and characters of several type of DNA molecule. We usually adopt different DNA molecule for different problem or models. Now, the main kinds of DNA molecules used in DNA computing are single, double and sticker terminal DNA molecules. Secondly£¬the DNA molecules used in DNA computing have also hairpin DNA molecules and plasmid DNA molecule. Especially, the relationship between the "data" (DNA molecule) and corresponding biomolecular model is disscuss.

keywords DNA computing; the structure and types of DNA molecules

background This research is supported by the National Natural Science Foundation of China (60533010, 30670540), and the National High Technology Research and Development Program(863 Program) of China (2006AA01Z104): Research on the Theory, Model and Method of DNA Computer etc. The projects mainly focus on DNA computer models for processing graphical messages, including encoding DNA sequences, synthesizing DNA molecules, setting up the model, detecting solutions, etc. The research group has been working on many aspects of DNA computing since 1996. They have published a monograph and more than 100 papers on DNA computing and DNA computer. In this paper, the authors present the Structure and Character of "Data" in DNA Computing. This is a basic theory in DNA computer.
