Describe the structure of nucleosomes and the 30-nm fiber, andexplain how the 30-nm fiber forms radial loop domains.
Unlike bacterial cells, the nucleus of a eukaryotic cell is bounded by a double-layered membrane studded by complex pores. How do you think this might affect traffic between the DNA and cytoplasm of a eukaryotic cell compared to that of a prokaryotic cell?
Explain linker domain
