Seberapa kecil Nucleosome?

Nucleosome memiliki diameter sekitar 11 nm.

Yang diukur: DNA wrapped around histone core

Nucleosome (11 nm) ditampilkan sesuai skala di samping a DNA double helix (2 nm) dan a ribosome (25 nm)
Digambar sesuai skala, dari kiri ke kanan: DNA double helix (2 nm), Nucleosome (11 nm), dan Ribosome (25 nm).

Bandingkan

Seberapa besar sebenarnya?

  • About 2 would fit across a ribosome
  • As wide as about 5 DNA double helices side by side
  • About 9 would fit across a flu virus
