In the study, investigators utilized nanoscale imaging and sensing technologies along with modeling techniques developed at Northwestern to individually label and observe chromatin fibers ...

2005). Histone sequences are highly conserved. The diagram in Figure 2 shows a typical chromatin fiber, with the blue cylinders representing histones. Extending from each of the histones is a ...

This experiment demonstrated that H2A, H2B, H3, and H4 form a discrete protein octamer, which is fully consistent with the presence of a repeating histone-containing unit in the chromatin fiber.
