A large amount of DNA can be packed into the small space inside the nucleus because the DNA is tightly wound around proteins called?

Explanation:
DNA fits into the nucleus by wrapping around protein bundles called histones. These histone proteins form an octamer around which about 146 base pairs of DNA coil to create a nucleosome, the basic unit of chromatin. This bead-on-a-string arrangement allows huge lengths of DNA to be packed tightly, and further folding of nucleosomes gives chromatin and, when cells divide, highly condensed chromosomes. The term histones refers to the actual proteins involved in this packaging, making it the correct choice. Nucleosomes are the DNA–histone complexes themselves, chromatins describes the broader DNA–protein mass, and chromosomes are the highly condensed forms during cell division.
