A) lysine; leucine; prions; ribosomes
B) arginine; lysine; histones; nucleosomes
C) arginine; alanine; histones; nucleosomes
D) arginine; lysine; prions; ribosomes
E) none are true.

Question

Quizplus · Accepted Answer

This describes the structure of nucleosomes, where histones interact with the DNA backbone to form bead-like structures. Choice A and D are incorrect because prions and ribosomes are not involved in DNA organization. Choice C is incorrect because alanine is not a positively charged amino acid like arginine and lysine, which are important in interacting with the negatively charged DNA backbone. Choice E is incorrect because there is a correct answer.
