  1. 1. Dynamics and Performance of a Linear Genetic Programming System

    Author : Frank D. Francone; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mutation; Genetic Programming; Homologous Crossover.; Crossover; Introns; Linear Genetic Programming; Code Bloat;

    Abstract : Genetic Programming (“GP”) is a machine learning algorithm. Typically, Genetic Programming is a supervised learning algorithm, which trains on labeled training examplesprovided by the user. The solution output by GP maps known attributes to the known labels. READ MORE

  2. 2. The deep evolutionary roots of non-coding RNA - a comparative genomics approach

    Author : Marc Patrick Hoeppner; Anthony M. Poole; Britt-Marie Sjöberg; Jürgen Brosius; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; non-coding RNA; evolution; comparative genomics; RNA world; introns; snoRNA; miRNA; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Abstract : Non-coding RNAs (ncRNA) are a diverse group of genes that do not encode proteins but function exclusively on the level of RNA and were originally suggested to be remnants of a pre-DNA stage of life known as the RNA world. More recent work, however, has uncovered a rich repertoire of previously unknown families with possible consequences for our understanding of the origin and evolution of the modern RNA infrastructure.

  3. 3. The relationship between orthology, protein domain architecture and protein function

    Author : Kristoffer Forslund; Erik Sonnhammer; Cristina Al-Khalili Szigyarto; Sarah Teichmann; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; homology; orthology; paralogy; gene duplications; protein function prediction; low-complexity regions; protein domains; domain architecture evolution; introns; intron position conservation; orthology conjecture; domain grammar hypothesis; biokemi; inriktning teoretisk kemi; Biochemistry with Emphasis on Theoretical Chemistry;

    Abstract : Lacking experimental data, protein function is often predicted from evolutionary and protein structure theory. Under the 'domain grammar' hypothesis the function of a protein follows from the domains it encodes. READ MORE

  4. 4. Group I Introns and Homing Endonucleases in T-even-like Bacteriophages

    Author : Linus Sandegren; Britt-Marie Sjöberg; Renée Schroeder; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bacteriophage; Self-splicing introns; Homing endonucleases; Molecular biology; Molekylärbiologi;

    Abstract : Homing endonucleases are rare-cutting enzymes that cleave DNA at a site near their own location, preferentially in alleles lacking the homing endonuclease gene (HEG). By cleaving HEG-less alleles the homing endonuclease can mediate the transfer of its own gene to the cleaved site via a process called homing, involving double strand break repair. READ MORE
