Abstract

The invention relates to the field of strand displacement, and discloses a two-dimensional probability distribution model based on DNA strand displacement. Calculation of combined probability distribution, edge probability distribution and condition probability distribution is achieved. A join door module is utilized to calculate a combined probability distribution law, and a transducer door module is utilized to calculate an edge probability distribution law. A condition probability can be directly obtained through a combined probability and an edge probability. A specific case is utilized to conduct simulation verification on the model, as is proved by tests, the model can accurately calculate three two-dimensional probabilities, the error is small, the reaction speed is high, the result is stable, and the effectiveness of the two-dimensional probability distribution model is proved.

Description

technical field [0001] The invention relates to a method for constructing a two-dimensional probability distribution model based on chain replacement, and belongs to the technical field of image processing. Background technique [0002] The principle of complementary base pairing between DNA molecules can make DNA molecules form various self-assembled structures. This process does not require external energy supply and is completely spontaneous. This characteristic of DNA makes it an ideal material in molecular computing. Utilizing the characteristic that DNA molecules can carry a large amount of information, it can be used as an information storage unit. DNA strand replacement technology is one of the most commonly used and important technical means in DNA molecular computing. It is applied in various fields and combined with various technologies to solve various practical problems, accelerate the development of molecular computing, and drive development in other fields. ...
