About 150 bp of DNA wrap around the histone octamer to form a bead-like structure.The "beads" are separated by about 50 bp of linker DNA.

Question

Quizplus · Accepted Answer

This is a well-established model of chromatin structure known as the "beads on a string" model. Each "bead" represents an octamer of histone proteins around which DNA is wrapped, and the linker DNA between each bead is approximately 50 bp in length.
