The association of histone H1 with a nucleosome indicates:

  1. A
    DNA replication is occurring
  2. B
    The DNA is condensed into a Chromatin Fibre
  3. C
    The DNA double helix is exposed
  4. D
    Transcription is occurring

Solution & Step-by-step Explanation

The H1 histone acts as a "linker" that pins the DNA to the histone octamer, facilitating the folding of the nucleosome chain into a higher-order chromatin fibre (30 nm fibre).
