All of the following statements concerning histones are true EXCEPT that they
A) are rich in arginine and lysine.
B) are proteins of relatively low molecular weight.
C) exhibit known interspecies homologies in their amino acid sequences.
D) are noncovalently attached to DNA in stoichiometric amounts.
E) exhibit a wide variety of non-homologous molecular structure.

Question

Quizplus · Accepted Answer

Histones are highly conserved proteins across species, meaning they exhibit significant homology in their amino acid sequences rather than a wide variety of non-homologous molecular structures. This conservation is crucial for their role in DNA packaging in the cell nucleus.
