||"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)."
||"The estimated stretch modulus (K)
was 870±140 pN (mean±SE,n=24), in good agreement
with the values of 800–1000 pN reported for ssDNA (18)". Note-in abstract value of 900pN is given, in body of article 870pN.
