Use "nucleosome" in a sentence
"The molecules that compact DNA are called the nucleosome core particles."
" The histones form a disk-shaped complex called a nucleosome which has two complete turns of double-stranded DNA wrapped around it."
"The resulting DNA/Histone complex, called a nucleosome subunit, is repeated tens of millions of times across the human genome to form chromatin, which is further compacted into ordered fibers 250-300 Angstroms in diameter (Refs 1-4)."
