One can calculate an entropic force by brute force from classical mechanics. Although the mean of the broad force distribution is equal to the entropic force, the most probable force is not.

Cells can grow everywhere, above or below a surface of either positive or negative Gaussian curvature as long as oxygen is around.

Le TT, Kim HD. Probing the elastic limit of DNA bendingNucleic Acids Research 2014;42(16):10786–94. PMID: 25122748 
We experimentally determined the angular limit of the famous worm-like chain model of DNA: DNA bends like an elastic rod only up to about 7 degrees per base pair. 

Le TT, Kim HD. Studying DNA looping by single-molecule FRETJournal of Visualized Experiments 2014;88. doi:10.3791/51667
A step-by-step video protocol on how to implement single-molecule FRET with one of the easiest systems around.

Modification of genomic DNA can bring about subtle effects because nucleosome positioning can be affected. 

Waters JT, Kim HD. Equilibrium statistics of a surface-pinned semiflexible polymer. Macromolecules 2013;46(16):6659–6666.
A few things to consider when experimenting with surface-attached polymers: looping dynamics of a polymer may become faster or slower depending on how it is confined.

Parikh RY, Kim HD. The effect of an intervening promoter nucleosome on gene expression. PLoS ONE 2013;8(5):e63072. PMID: 23700413
Because nucleosomes compact DNA inside the cell, they are thought to hinder reading of the genetic code. Here, we propose an intriguing mechanism of how nucleosomes may help decode the genetic code.

Le TT, Kim HD. Measuring shape-dependent looping probability of DNA. Biophysical Journal 2013;104(9):2068–2076. PMID: 23663850
Which DNA loops faster, a C-shape or an S-shape? We measured looping probabilities of DNA molecules of different curvatures.
