Fluorescence polarization study of tertiary structure of DNA within bacteriophage lambda
FEBS Letters
|January 9, 1984
Abstract:
The fluorescence polarization of acridine orange-stained, oriented lambda phages was measured. The parameters of DNA packing within the phage head cos2 theta and cos4 theta were calculated (theta, angle between the direction of a small segment of DNA and the phage axis). It is shown that simple models of lambda phage DNA tertiary structure are not consistent with calculated values. A new model is proposed.
