  • [4] The road outside the new building is named Francis Crick Avenue after the 1962 joint Nobel Prize winner and LMB alumnus, who co-discovered the helical structure of DNA in 1953. (wikipedia.org)
  • Watson and Crick discovered the double-helical structure of DNA , which revealed that biological information was encoded in a linear structure and how this information could be duplicated during cell division . (wikipedia.org)
  • Our characterization of pol β from a model fish organism contributes to the study of the function and evolution of DNA polymerases, which are emerging as important cellular targets for chemical intervention in the development of anticancer agents. (biomedcentral.com)
  • However, the drugs also interact with other enzymes, e.g. topo I, DNA- and RNA polymerases, and helicases. (allindianpatents.com)
  • When it combines with CRISPR and gRNA, it specifically cleaves DNA at a programmed location (at target sequence). (geneticeducation.co.in)
  • We therefore studied the association of two polymorphisms - R353Q polymorphism at codon 353 involving the catalytic region and the 10 base pair (bp) insertion polymorphism involving the promoter region - with FVIIc levels in 176 healthy Tunisians. (who.int)
