Verified step by step guidance

Understand the structure and organization of genetic material within a cell. DNA is the fundamental unit of genetic material, consisting of nucleotide sequences.

Recognize that nucleosomes are the next level of organization. They are complexes of DNA wrapped around histone proteins, forming the basic unit of chromatin structure.

Identify chromatin as the material that makes up chromosomes. It consists of DNA and protein, including nucleosomes, and is found in the nucleus of eukaryotic cells.

Understand that chromosomes are the highest level of organization of genetic material. They are structures that contain chromatin and become visible during cell division.

Arrange the genetic material from smallest to largest based on their structural complexity: DNA, Nucleosomes, Chromatin, Chromosomes.
