Nucleosomes are complexes of:

  1. a. RNA and DNA
  2. b. RNA and histone
  3. c. histones and DNA
  4. d. DNA, RNA, and protein
  5. e. amino acids and DNA

Summary Introduction

Introduction: Chromosomes are uncoiled and re-coiled during cell division. When a cell moves from interphase to mitosis, chromosomes are uncoiled and re-coiled. The DNA is uniquely arranged in the nucleus to regulate the genetic information.

Explanation of Solution

Reason for correct answer:

Nucleosome is the basic unit of DNA packing in eukaryotes. DNA is wrapped around the histone core proteins in the nucleosomes. The nucleosomes look like beads on a string. Approximately, 147 base pairs of DNA wounds around the nucleosome core particle.

Option c. is given as “histones and DNA.”

The DNA wounds around a histone molecule to form spherical bodies (nucleosomes). Nucleosomes are the complexes, which are made up of histones and DNA. Hence, the correct answer is option c.

Reasons for incorrect answer:

Option a. is given as, “RNA and DNA.”

RNA is a ubiquitous biomolecule which is present in the nucleus and cytoplasm. Nucleosomes do not have RNA...
