Final answer:
Eukaryotic DNA is packed with nucleosomes through a process called chromatin packaging, where the DNA is tightly wrapped around histone proteins at repeated intervals. This compacts the DNA and allows for efficient storage and organization in the nucleus of eukaryotic cells.
Step-by-step explanation:
Eukaryotic DNA is packed with nucleosomes through a process called chromatin packaging. The DNA is tightly wrapped around histone proteins at repeated intervals, forming structures called nucleosomes. Each nucleosome consists of eight histone proteins around which the DNA is wound. These nucleosomes are further compacted into a 30nm fiber, providing significant compaction of the DNA. This packaging allows for the efficient storage and organization of the long DNA molecules in the nucleus of eukaryotic cells.
