Inspired by the structure of the potassium channel "origami windmill" model, and combining the multi-strand folding characteristics of DNA molecules, ion regulation mechanisms, and genetic information transmission rules, a four-strand DNA inverted cone windmill model is proposed, breaking through the linear structural limitations of the traditional double helix model.The model utilizes a four-stranded DNA core scaffold, forming a windmill-like radial spatial conformation through a "double ladder inverted" mechanism. The strands are stabilized by hydrogen bonding, base stacking, and ionic regulation, while relying on the "single ladder inheritance"mechanism to achieve precise transmission of genetic information.This article elaborates on the construction lineage, structural characteristics, genetic mechanism, and potential biological significance of the model, providing a new perspective for the study of DNA multi-strand structure and genetic regulation.
