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 is a coverage gap provision that allows you to remain on an employer's group health insurance policy by paying the entire premium up to 102 percent of the original coverage cost. You can maintain COBRA coverage for up to 18 months, although disability and other provisions can allow further extension. Maintaining this coverage allows you to benefit by keeping previously paid deductibles and will help you avoid the pre-existing condition limitations of buying new coverage.
