"large molecule" is pretty misleading. DNA is single molecule and unrolled has length over 2 meters. Organic molecules are practically unlimited in their size.

Alberts et al. Textbook. "Each human cell contains approximately 2 meters of DNA if stretched end-to-end" Perhaps a human cell contains several DNA molecules?
- Crito 13y agoEach human cell typically contains 23 chromosomes, each of which is basically a long DNA strand. This indicates that the total length unraveled is 2m: https://www.inkling.com/read/essential-cell-biology-bruce-alberts-3rd/chapter-5/the-structure-of-eucaryotic https://www.inkling.com/read/essential-cell-biology-bruce-al...
- dekhn 13y agotechnically correct but they are talking about touching the accessible surface of a compact molecule which is approximately spherical and thus "size" is determined by its raised profile on a surface.
