1. Telomeric DNA in Chironomus, a naturally telomerase-free system
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
2. Saccharomyces castellii: A new model organism for telomere research
Sammanfattning : Telomeres are natural ends of eukaryotic chromosomes and perform a major role in cell biology. They protect chromosomes from degradation, fusions and the end replication problem. To study telomeres different model organisms are used including a number of yeast species. LÄS MER
3. Functional Studies of Telomere-Binding Proteins in Saccharomyces castellii
Sammanfattning : Telomeres are the ends of linear eukaryotic chromosomes. The telomeres are essential for solving the end replication problem and they stabilize the genome by protection from degradation. The telomeres also protect the chromosomal ends from by being recognized as DNA breaks by the repair machinery, which could lead to end-to-end fusions. LÄS MER
4. The maintenance of telomeres in the budding yeast Naumovozyma castellii
Sammanfattning : Linear chromosomes of eukaryotic cells require the presence of functional nucleoprotein terminal structures, known as telomeres, to protect the integrity of the genome. The telomere is a highly dynamic and regulated structure constituted by short tandem DNA repeats rich in guanine nucleotides that extent as double-stranded DNA ending in a single-stranded 3′ overhang.

5. Molecular characterization of the interplay between DNA-PK and TRF2 in telomere protection
Sammanfattning : The genetic material of mammalian cells is organized as linear chromosomes inside their nucleus. In order to preserve genomic stability, mammalian cells have developed several mechanisms to detect and repair DNA lesions that can occasionally occur in the genome. LÄS MER
