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

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

    Sammanfattning : 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.

  2. 2. The evolution of ribonucleotide reductases

    Författare :Daniel Lundin; Anthony Poole; Britt-Marie Sjöberg; Christos Ouzounis; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolution; ribonucleotide reductase; horizontal gene transfer; phylogeny; protein classification; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : Ribonucleotide reductase (RNR) catalyses the transformation of RNA building blocks, ribonucleotides, to DNA building blocks, deoxyribonucleotides. This is the only extant reaction pathway for de novo synthesis of DNA building blocks and the enzyme is thus necessary for life. RNR is found in all but a few organisms. LÄS MER

  3. 3. The evolution of the nuclear envelope

    Författare :Nadja Neumann; Anthony Poole; Gáspár Jékely; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear pore complex; bouquet; meiosis; nucleus; eukaryote evolution; nucleoporin; tree of life; stem group; recombination; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : The nucleus is one of the defining features of eukaryotes and the question of its origin is intimately linked to the evolution of the eukaryotic cell. It is delimited by a double lipid bilayer called the nuclear envelope, which separates the nuclear interior from the cytoplasm. LÄS MER
