Method for selecting nucleic acids on the basis of structure
First Claim
1. A method for identifying nucleic acid molecules from a candidate mixture of nucleic acids on the basis of a specific structural characteristic, comprising:
- a) subjecting said candidate mixture of nucleic acids to partitioning;
b) selecting nucleic acids having said specific structural characteristic as determined by their partitioning behavior;
c) amplifying the selected nucleic acids to yield an amplification mixture enriched for nucleic acids having the specific structural characteristic;
d) repeating steps b) and c), whereby nucleic acid molecules having said specific structural characteristic may be identified.

Abstract
A method of selecting nucleic acids on the basis of physical structure is disclosed. A modification of the Systematic Evolution of Ligands by Exponential enrichment (SELEX) is used in conjunction with methods for differentiating between nucleic acid molecules on the basis of physical structure, such as chromatography, gel electrophoresis, solubility, and solvent partitioning. The disclosed method may be used in selecting single stranded DNA or RNA, or double stranded DNA or RNA. An example of the method selected nucleic acids of bent DNA. This method represents a new and powerful approach to select nucleic acid molecules with the physical structure required for specific biological activity, for example, in the regulation of gene expression.
