Linker-DNA is attached to

Options

  1. AH ₁
  2. BH ₂ ~A
  3. CH ₂ ~B
  4. DH ₃

Correct answer

A. H ₁

Step-by-step solution

Linker-DNA is attached to H ₁ histone length. Linker DNA connects two adjacent nucleosomes. Its length is varied (about 145 Å with 70 bp). Nucleosome and linker DNA together constitute chromatosome. Chromatosome contains a histone octamer and DNA.
