The Role Of Rad4 In Dna Repair And Its Interplay With Telomeres In Tetrahymena Thermophila, Emily Nischwitz

MSU Graduate Theses

Telomeres are repetitive parts of the genome that act as a protective end cap to the chromosomes. Telomeres are critical to the integrity and stability of the genome, therefore, ensuring that their sequence is maintained, even after damage, is crucial. Much of the pioneering work responsible for explaining telomeres has been conducted in ciliates, specifically in Tetrahymena thermophila. Telomeres in T. thermophila have a high amount of tandem thymine repeats (GGGGTT) and, thus, are susceptible to ultraviolet light (UV) induced lesions called pyrimidine dimers, which must be repaired by nucleotide excision repair (NER). In humans, Xeroderma Pigmentosum C (XPC) …
