Question

What is the typical range for linker DNA length between nucleosomes?

Options

• 20–90 base pairs

• 146 base pairs

• 100–150 base pairs

• 1–20 base pairs

Answer 1

Linker DNA, which connects adjacent nucleosomes, typically ranges from 20 to 90 base pairs in length. This range varies depending on the species and tissue type, and the specific length influences higher-order chromatin structure and gene expression regulation. Histone H1 binds at the entry and exit sites of this linker DNA.
