  2. 1. Synthesis and modifications of materials for separation science

    Author : Anna Nordborg; Knut Irgum; Michael Lämmerhofer; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; material synthesis; monolith; surface modification; telomer; “grafting to”; gradient polymer elution; chromatography; Chemistry; Kemi;

    Abstract : This thesis deals with the preparation of materials for use in separation science and their surface modification by grafting. The overall aim is the preparation of diverse materials by combination of a set of developed tools. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. PARN – The Tail End : Function and mechanisms of specificity and processivity

    Author : Mikael Nissbeck; Anders Virtanen; Renée Schroeder; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Poly A specific ribonuclease; Adenosine; Specificity; Processivty; Telomere biology disorders; Molekylär cellbiologi; Molecular Cellbiology;

    Abstract : Poly(A)-specific ribonuclease (PARN) is an exoribonuclease that is processive, poly(A) specific and cap-binding. PARN deadenylates the poly(A) tails present on a subset of mRNAs and non-coding RNAs, including among others certain snoRNAs, miRNAs and precursor rRNAs. READ MORE

  6. 4. RAP1 at the Yeast Telomere

    Author : Johan Wahlin; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytogenetik; DNA-binding; Saccharomyces; yeast; telomeric repeat; telomere; RAP1; repressor activator protein 1; Genetics; cytogenetics; Genetik;

    Abstract : Telomeres are specialized complexes of DNA and proteins that cap and confer stability to the ends of eukaryotic chromosomes. The telomeric DNA of most eukaryotes is composed of tandemly arranged short repeats. Within the budding yeasts these repeats are diverged in length as well as in nucleotide composition. READ MORE

  7. 5. Classes of DNA associated with telomeres in the chironomids C. pallidivittatus and C. tentans

    Author : Iréne Kamnert; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genetics; Chironomus; subtelomere; gene conversion; subfamilies; telomere; complex repeats; cytogenetics; Genetik; cytogenetik;

    Abstract : Telomeres in Chironomus consist of long complex tandem DNA repeats, which in C. pallidivittatus have been shown to extend to the extreme end of chromosomes. In C. pallidivittatus the telomeric repeats are present in large blocks, 50-200kb in size, most of them belonging to four major subfamilies. READ MORE
