  1. 1. Telomeric DNA in Chironomus, a naturally telomerase-free system

    Författare :Monika Rosén; Udo Häckers grupp Utvecklingsbiologi i invertebrater; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Chironomus; extrachromosomal telomeric repeats; RNA-DNA complex; 3´overhang; telocentric chromosome end; Telomere; complex repeats; Biologi; Genetics; cytogenetics; Genetik; cytogenetik;

    Sammanfattning : Telomeres are specialized complexes of DNA and associated proteins that protect the ends of eukaryotic chromosomes. Although most organisms have short repeated DNA sequences at their telomeres, which are specified and maintained by the enzyme telomerase, there are a few exceptions. LÄS MER

  3. 2. Repetitive DNA in search of a function - a study of telomeric and centromeric sequences in Chironomus

    Författare :Casimiro Castillejo-Lopez; Udo Häckers grupp Utvecklingsbiologi i invertebrater; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chironomus; CENP-B box; mobile elements; reverse transcriptase; gene conversion; satellite; repetitive DNA; Telomere; centromere; Genetics; cytogenetics; Genetik; cytogenetik;

    Sammanfattning : Repetitive DNA is quantitatively the main component of telomeres and centromeres, structures responsible for maintenance of the eukaryotic chromosome. The telomere is the specialized nucleoprotein complex that terminates linear chromosomes. LÄS MER

  4. 3. Cytoskeletal Regulation During Embryonic Development in Drosophila melanogaster

    Författare :Mojgan Padash; Udo Häckers grupp Utvecklingsbiologi i invertebrater; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Naturvetenskap; Natural science; DRhoGEF2; Actin cytoskeleton; Rho GTPase;

    Sammanfattning : The development of multicellular organisms is associated with extensive rearrangements of cells and tissues. The driving force for these rearrangements is generated by the cell's actin cytoskeleton. During many morphogenetic processes dynamic rearrangement of the actin cytoskeleton is regulated by small GTPases of the Rho-family. LÄS MER
