A circular dichroism technique for the determination of DNA base composition in terms of the guanine-cytosine content has been developed. A linear relationship between the ratio of ellipticities at 260 and 280 nm (theta 260/theta 280) and base composition of DNA is obtained in citrate-phosphate buffer, pH 3.0 at 20 degrees C. The DNA base composition obtained with this method is not only highly reproducible but is also the fastest method reported.
