The beads are called nucleosomes. Each nucleosome is made of DNA wrapped around eight histone proteins that function like a spool and are called a histone octamer. Each histone octamer is composed ...

The basic organizational unit of the genome is a nucleosome, which is a short segment of DNA wound around a complex of eight histone subunits. Each of these histones has a tail region which can be ...

Approximately 50% of chromosomes and chromatin is protein. These include histones, transcription factors, nuclear receptors, co-activators, co-repressors, histone modifying enzymes, nucleosome binding ...
