In addition to its conceptual importance in physics, a random walk is a surpisingly good model for some biophysical problems. This talk will present several examples, including DNA conformation and protein motion along a biopolymer, that are well described by a biased or unbiased random walk. I will discuss the physical theory and biophysical applications of several problems from our recent research: finite-length effects in DNA elasticity, the coupling of a biased walker with a fluctuating wall and collective effects that occur when multiple walkers change the length of a track.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u0022Random Walks, DNA Elasticity, and the Motion of Proteins\u0022\u003C\/p\u003E\u003Cp\u003EMeredith Betterton, PhD - University of Colorado at Boulder\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Meredith Betterton, PhD - University of Colorado at Boulder"}],"uid":"27195","created_gmt":"2011-03-09 14:06:22","changed_gmt":"2016-10-08 01:54:30","author":"Colly Mitchell","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2011-03-14T16:00:00-04:00","event_time_end":"2011-03-14T17:00:00-04:00","event_time_end_last":"2011-03-14T17:00:00-04:00","gmt_time_start":"2011-03-14 20:00:00","gmt_time_end":"2011-03-14 21:00:00","gmt_time_end_last":"2011-03-14 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/spot.colorado.edu\/~mdb\/","title":"Betterton profile"}],"groups":[{"id":"1292","name":"Parker H.
