AbstractDirect observations of fine structure of DNA bundles were presented in this paper. These DNA bundles existed originally in lambda -DNA solution with a high concentration of 480ng/mul. When this solution was diluted. DNA bundles finally split into individual DNA molecules. DNA bundles were stretched on mica treated with 3-animopropyl triethoxysilane (APS) and observed by an atomic force microscope (AFM), A method was developed to avoid the possible artifacts during the drying process in,,ample preparation. It was found that in a bundle composed of two individual DNA molecules, these two molecules wound around each other in a helical path.
