  • SWISS-PROT kept the name TREMBL for their Translation of EMBL CDS, since the tools used to create the translations of the CDS are based on the program 'trembl' written by Thure Etzold at the EMBL in Heidelberg. (bio.net)
  • Thure translates all CDS in the EMBL nucleotide sequence database into TREMBL entries. (bio.net)
  • [7] [8] One of the early attempts at predicting RNA secondary structure was made by Ruth Nussinov and co-workers who developed a dynamic programming-based algorithm that maximized the length and number of a series of "blocks" (polynucleotide chains). (wikipedia.org)
