Nucleosome positioning in the somatic
macronuclear genome of the ciliated protozoan Tetrahymena
thermophila was analyzed by indirect end labeling. Nucleosomes
were positioned nonrandomly in three different regions of the
Tetrahymena genome. Nucleosome repeat length varied between
adjacent nucleosomes. Nucleosome positioning in a histone H1 knockout
strain was indistinguishable from that in a strain with wild type
histone H1.
