We address two questions related to this process. 1) How much information could have been encoded in prebiotic replication? The rate at which errors are made during replication imposes a theoretical limit on the amount of information that can be faithfully propagated (Eigen\u0027s error threshold). We show how this threshold could be postponed in a realistic prebiotic scenario and estimate the magnitude of this effect in an experimental system.  2) Could chemical mechanisms alone drive\u003Cbr \/\u003E\nan increase in complexity? We demonstrate how prebiotic mechanisms in nucleic acid polymerization could predispose the system toward complex sequences.\n\u003C\/p\u003E\n\u003Cp\u003EFor more information contact \u003Ca href=\u0022mailto:loren.williams@chemistry.gatech.edu\u0022\u003EProf. Loren Williams\u003C\/a\u003E (404-894-9752).\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Prof. Irene Chen, Harvard University\n\nInformation in the Prebiotic World\n\nRiboEvo Special Seminar","format":"limited_html"}],"field_summary_sentence":[{"value":"Prof. Irene Chen, Harvard University"}],"uid":"27275","created_gmt":"2010-04-19 00:00:00","changed_gmt":"2016-10-08 01:47:50","author":"Shirley Tomes","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2010-10-05T17:00:00-04:00","event_time_end":"2010-10-05T18:00:00-04:00","event_time_end_last":"2010-10-05T18:00:00-04:00","gmt_time_start":"2010-10-05 21:00:00","gmt_time_end":"2010-10-05 22:00:00","gmt_time_end_last":"2010-10-05 22:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/sysbio.harvard.edu\/csb\/Chen_Lab\/index.htm","title":"Prof. Irene Chen, Harvard University"}],"groups":[{"id":"85951","name":"School of Chemistry and Biochemistry"}],"categories":[],"keywords":[{"id":"89","name":"chemistry"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EShirley Tomes\u003C\/strong\u003E\u003Cbr \/\u003EChemistry \u0026amp; Biochemistry\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=st81\u0022\u003EContact Shirley Tomes\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-0591\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
