Eukaryotic genomic DNA exists as highly compacted nucleosome arrays called chromatin. Each nucleosome contains a 147-base-pair (bp) stretch of DNA, which is sharply bent and tightly wrapped around a ...
Eukaryotic genomes are packaged into chromatin, whose basic repeating unit is a nucleosome that consists of a histone octamer wrapped around 147 base pairs (bp) of DNA 1. Nucleosomes are arranged into ...
