Primary source abstract: "A novel optical method was built to control the position of the laser trap along the microscope optical axis at 2 nm resolution, facilitating measurement of the force-extension relationship for poly(U)." |
| Comments |
Supplementary online material p.6 top paragraph: "If [investigators] assume that the mRNA in such conditions (of zero external applied force) will behave as a Worm Like Chain (Kratky and Porod, 1949) with a persistence length of 0.79 nm measured experimentally for mRNA-ribosome complexes (primary source), [they] can find the number nucleotides that gives a root mean squared value of the end-to-end distance equal to 7.35 nm." |
