WebBelow, for convenience, we will mainly use persistence lengths rather than bending rigidity constants converting one to another according to Eq. 1. We addressed the problem using the dinucleotide approxima-tion. Thus, the total bending energy, E, of DNA fragment of n base pairs in length is specified as E ¼ kT 2l ∑ n−1 i¼1 aiθ2 i; [2] Web7. dec 2024 · Then we can use following formula to calculate the persistence length. $ l_{p} = \frac{\sum_{1}^{n}l_{1}.l_{n}}{l} . $ I have taken this formula from reference 1. My issue is that it works fine in the case if track does not change direction more than 90 degrees. If this change happens in the start of the track, I get negative persistence length ...
