Abstract:
Objective To compare the effects of three different methods for extracting short RNA-DNA hybrids, including the TRI reagent method , the phenol saturated with water method and the phenol saturated with Tris buffer method in order to facilitate studies on the biological function of RNA-DNA hybrids .Methods Short RNA fragments modifiedwith FAM at the 5′end and those modified with Cy 5 at the 5′end were synthesized .RNA and DNA fragments were annealed to form RNA-DNA hybrids.They were extracted with the above-mentioned 3 methods respectively .The extracted products were analyzed with electrophoresis .Results and Conclusion Short RNA-DNA hybrids can be extracted by the phenol saturated with water method and by the phenol saturated with Tris buffer method .The results can help study the function of short RNA-DNA hybrids .
