histone / histones. Under the microscope in its extended form, chromatin looks like beads on a string. The beads are called nucleosomes. Each nucleosome is made of DNA wrapped around eight histone proteins that function like a spool and are called a histone octamer.nder the microscope in its extended form, chromatin looks like beads on a string.

A health plan may provide longer periods of coverage beyond those required by COBRA. Under COBRA, an individual may be entitled to up to 18 months, 29 months, or 36 months of continuation coverage depending upon which qualifying event(s) triggered the COBRA coverage. The following table illustrates the maximum coverage periods for each qualifying event.
COBRA coverage generally is offered for 18 months, and 36 months in some cases. If you don't get a notice, but you find out your coverage has ended, or if you get divorced, call the employer's benefits administrator or the group health plan as soon as possible and ask about your COBRA rights.
