Final answer:
In eukaryotes, DNA is wrapped around histones to form d. nucleosomes.
Step-by-step explanation:
Eukaryotes, whose chromosomes each consist of a linear DNA molecule, employ a different type of packing strategy to fit their DNA inside the nucleus. At the most basic level, DNA is wrapped around proteins known as histones to form structures called d. nucleosomes.
The DNA is wrapped tightly around the histone core. This nucleosome is linked to the next one with the help of a linker DNA. This is also known as the 'beads on a string' structure.
