Question

DNA is divided into multiple linear chromosomes, which, together with proteins, are organized into a complex structure called?

1) Nucleus
2) Cell membrane
3) Cytoplasm
4) Nucleosome

Answer 1

DNA is organized into nucleosomes, structures in which DNA wraps around histone proteins, and these together form chromatin when not condensed into chromosomes.

Step-by-step explanation:

DNA in eukaryotic cells is divided into multiple linear chromosomes, which, together with proteins, are organized into a structure known as a nucleosome. The DNA is wound around histone proteins, creating a complex that resembles beads on a string. When the cell is not dividing, this structure remains decondensed and is called chromatin. However, it condenses into chromosomes to facilitate the safe transportation of DNA during cell division. The correct answer to the question is option 4) Nucleosome, since that is the name of the complex structure formed by DNA wrapped around histone proteins.
