Range ≤50 pN
Organism Bacteriophage

Method laser tweezer measurements
Comments P.411 left column bottom paragraph:"The force needed to package the genome against this resistance is provided by a virally encoded motor protein that pushes in the DNA along its length. Recent laser tweezer measurements (ref 12) have confirmed that this force increases progressively as packaging proceeds, i.e., as the chain becomes more crowded and bent, reaching values as large as 50 pN upon completion."
