1. Chromatin transcription and dietary proteins : with observations on the RNA synthesis of rat liver in response to the protein content and amino acid composition in the diet
Sammanfattning : This thesis aims at characterization of fractionated chromatin with respect to bound and free RNA polymerase activities together with an analysis of the in vitro transcription of chromatin after changing the protein or amino acid content of the diet.Rat liver nuclei were incubated with micrococcal nuclease which acts as an endonuclease on DNA.

2. Guardians of the genome : Connecting chromatin structure and genome integrity in Saccharomyces cerevisiae
Sammanfattning : Branched DNA structures arise during recombination and during other DNA repair processes such as repair of stalled replication forks. One branched structure, the Holliday Junction (HJ), is a four-way junction that can connect sister chromatids or homologous chromosomes. We show a physical interaction between the HJ-cleaving enzyme Yen1 and Uls1. LÄS MER
