A)nucleus attached to the ends of DNA strands.
B)nucleus and are composed of DNA and histones.
C)nucleus and are associated with the nuclear membrane.
D)nucleus and are composed of mRNA and histones.
E)nucleus and are associated with the nucleolus and aid in ribosome synthesis.

Question

Quizplus · Accepted Answer

Nucleosomes are composed of DNA and histones and are located in the nucleus. They help in the packaging of DNA by wrapping it around the histones, forming a bead-like structure.

Option A is incorrect because nucleosomes are located throughout the DNA strand, not just at the ends.

Option C is incorrect because nucleosomes are not associated with the nuclear membrane.

Option D is incorrect because nucleosomes are not composed of mRNA; they are composed of DNA and histones.

Option E is incorrect because nucleolus is primarily involved in ribosome synthesis, and nucleosomes do not aid in this process.
