Chromatin of eukaryotes is organized into repeating interactions with protein octamers called nucleosomes.Nucleosomes are composed of which class of molecules?
A)histones
B)H1 histones
C)glycoproteins
D)lipids
E)nonhistone chromosomal proteins

Question

Quizplus · Accepted Answer

Nucleosomes are composed of histones, which are a class of proteins that package and organize DNA in eukaryotic cells. H1 histones and nonhistone chromosomal proteins may also be involved in chromatin organization, but the primary components of nucleosomes are the core histones (H2A, H2B, H3, H4). Glycoproteins and lipids are not involved in nucleosome formation or chromatin organization.
