Anna Capasso,Alberto Loizzo,Sergio Caroli that bacterial DNA is indeed organized in nucleosomelike structures by histonelike proteins. Since the problem of the physical packaging and confinement of the genetic material can be regarded as a fundamental problem in all biological systems and in light of the underlying architectural unity of a

Handbook of hair in health and diseaseevidence that prokaryotic chromosomes are folded in a nucleosomelike structure has led to a search for hist onelike proteins and to the development of methods to lyse bacterial cells mildly. Using these techniques, several authors have isolated deoxyribonucleoprotein complexes (DNP) and purified a n

Romanists will, I trust, forgive the plagiarism in the title; it is borrowed from a recent Italian Prime Minister and presents an antinomy that is remarkable both for its insolence and for its profundity, and which, I believe, describe
