Core particle stability critically depends upon a small number of terminal nucleotides
Biophysical Chemistry
|October 1, 1981
Abstract:
An apparently homogeneous population of core particles is in fact composed of three subpopulations which behave differently when exposed to a high concentration of ethidium bromide or to 0.6 M NaCl. These subspecies have been identified by the use of several techniques, viz., electron microscopy, sedimentation velocity and circular dichroism. The electrophoretic analysis of their DNA leads to the conclusion that core particle stability critically depends upon a small number of terminal nucleotides.
