The correct answer is option 2: DNA and Protein.
Eukaryotic chromatin is the complex of DNA and proteins that make up the chromosomes within the nucleus of eukaryotic cells. DNA is the genetic material of the cell and contains the instructions for the cell`s functions and development. Proteins play a crucial role in the organization and regulation of DNA within the nucleus. The primary protein components of eukaryotic chromatin are called histones, which help package the DNA into a highly compact and organized structure.
Histones form a structural framework by wrapping the DNA around them, forming nucleosomes. Nucleosomes are the basic units of chromatin and consist of DNA wound around an octamer of histone proteins. These nucleosomes are further organized into higher-order structures, such as chromatin fibers and chromosomes.
While RNA does play a role in gene expression and regulation, it is not a structural component of eukaryotic chromatin. RNA molecules are transcribed from DNA and participate in various cellular processes, including protein synthesis.
Therefore, the correct composition of eukaryotic chromatin is DNA and protein. Alert - correct answer should be option 2: DNA and Protein.
