[Detection of DNA packing density in bacteriophages Phi KZ and T4 by atomic force microscopy]. / Opredelenie plotnosti upakovki DNK u bakteriofagov Phi KZ i T4 metodami atomnoi silovoi mikroskopii.

ABSTRACT

Comparative analysis of DNA packing density in Phi KZ and T4 bacteriophages was carried out by atomic force microscopy. Irrespective of the support (mica or highly ordered pyrrolytic graphite), Phi KZ bacteriophage was compressed stronger than T4. The most probable causes of this difference are analyzed.
