Ribosome
D
Golgi apparatus
Verified step by step guidance
1
Understand the role of DNA and histones in eukaryotic cells. DNA is the genetic material that carries the instructions for the development, functioning, growth, and reproduction of all known organisms. Histones are proteins that help package and order DNA into structural units called nucleosomes.
Identify the eukaryotic structure that contains DNA and histones. In eukaryotic cells, DNA is organized into chromosomes, which are located in the nucleus. Histones are associated with DNA in the nucleus to form chromatin.
Review the functions of the listed structures: The nucleus is the organelle that houses the cell's DNA and is the site of DNA replication and transcription. The endoplasmic reticulum is involved in protein and lipid synthesis. Ribosomes are the sites of protein synthesis. The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids.
Recognize that the nucleus is the only structure among the options that contains DNA and histones. The other structures have different functions and do not contain DNA or histones.
Conclude that the correct answer is the nucleus, as it is the eukaryotic structure that contains both DNA and histones.
