What is meant by the "beads on a string" model of chromatin?

▸ The beads are the histones, and the string is the transcriptionally active DNA loops.

▸ The beads are the nucleosomes, and the string is the linker DNA.

▸ The beads are molecules of DNA polymerase that attach to the DNA string.

▸ The beads are ribosomes, and the string is the mRNA that has been transcribed from active chromatin.

▸ The beads are the heterochromatic regions that are tightly compacted, and the strings are euchromatic regions that are being actively transcribed.
