  2. 1. Amelioration of Horizontally Transferred Genes

    Author : Torbjörn Karfunkel; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transposoner; horisontell genöverföring; dna; bakterier; plasmider;

    Abstract : The importance of Horizontal (Lateral) Gene Transfer has attracted much attention during the last few decades. It is a very important factor in bacterial evolution and ecology, and it has great implications on human life as well. READ MORE

  4. 2. 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

  5. 3. Transcription, splicing and genetic structure within the human endogenous retroviral HERV-H family

    Author : Mats Lindeskog; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; immunosuppressive envelope protein; RNA splicing; Human endogenous retrovirus; transcription; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Human endogenous retroviruses (HERVs) are remains of ancient retroviral infections of the germ line and constitute as much as 3 % of the human genome. HERVs are genetic elements that potentially may provide important biological functions by several different mechanisms. READ MORE

  6. 4. 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
