1. Repetitive DNA in search of a function - a study of telomeric and centromeric sequences in Chironomus
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
2. The exploration and evolution of the avian genomic dark matter
Sammanfattning : The development and improvement of genome sequencing technologies in the last decade revolutionised the entire field of biology with genome assemblies of virtually any organism. Despite this tremendous progress, complex genomic regions are systematically missing from genome assemblies and form the so-called "genomic dark matter". LÄS MER
3. Genotyping RNA and DNA using padlock probes
Sammanfattning : Novel techniques are needed to investigate the genetic variation revealed in the first draft of the human genome sequence. Padlock probes are recently developed reagents, suitable for detecting single-nucleotide variations of DNA and RNA in situ or in solution. LÄS MER
4. Interactions of satellite phage P4 with its helpers : P2 and WΦ phages
Sammanfattning : Bacteriophage P4 is a defective phage that needs a helper phage to grow lytically, since it lacks structural genes and genes encoding host cell lysis functions. P4 has the capacity to derepress the unrelated prophage P2, or its relatives after infection, thereby getting access to the late functions of the helper. LÄS MER
5. Padlock probes : Circularizing oligonucleotides for localized detection of DNA sequence variants
Sammanfattning : Present techniques for localized detection of DNA sequence variants have limitations due to problems with sensitivity, specificity, signal localization or ability to perform many analyses simultaneously.In this study a novel gene analytic reagent is presented - the padlock probe.
