TI  - A Minimum Estimate for the Length of the DNA of Escherichia Coli obtained by Autoradiography
N2  - E. coli labelled with [3H]thymine was lysed in EDTA and 2 M-sucrose by dialysis against Duponol. After 20 hours the DNA of some bacteria had partly untangled and was trapped on the wall ofthe dialysis membrane when the dialysis chamber was drained. Autoradiography showed this DNA to be several hundred microns long, indicating a molecular weight of 109 or more. Short fragments, which would correspond to the usual molecular weight of extracted bacterial DNA, were not seen
