Oligonucleotide Fingerprinting of Ribosomal RNA Genes (OFRG)
and Microorganism Classification

Brief Introduction

The oligonucleotide fingerprinting of ribosomal RNA genes(OFRG) is a method that permits the identification of arrayed ribosomal RNA genes (rDNA) through a series of hybridizaition experiments using small DNA probes. It provides a cost effective means to extensively analyze microbial communities and should have application in medicine, biotechnology and ecosystem studies. This project is funded by NSF DBI.
