Aortic Response to Various Effects,ells of higher eukaryotes to repair this lesion, nonhomologous end-joining (NHEJ) is the most dominant. The biochemical characterization of NHEJ has significantly benefited from in vitro plasmid end-joining assays that can complement and extend information obtained from genetic studies.

We have developed gene targeting methods that we have specifically used to investigate the mechanisms of recombination in cultured mammalian cells. In this chapter, we describe the generation o无能力 发表于 2025-3-27 15:37:17
William D. Wagner,Thomas B. Clarksonth high reproducibility. Specific nicking and loss of a restricted DNA fragment at the site of induced damage is visualized by Southern blot and quantified against a control; since the blot is gene specific, only the damage of interest is measured. Here we show how the assay may be adapted to assessABHOR 发表于 2025-3-27 18:06:24

Jack C. Geer,William S. Webster the genome is modulated by the DNA sequence, by DNA methylation patterns, by the transcriptional status of the locus, and by chromatin proteins associated with the DNA. The only method currently available to allow a precise sequence mapping of DNA lesions in mammalian cells is the ligation-mediated有其法作用 发表于 2025-3-28 03:10:52
Wolfgang Schaper,Dimitri Scholzeous genetic damage has developed. This, in turn, has increased interest in the cellular mechanisms responsible for tumorigenesis, and the need to develop experimental methodologies to investigate these mechanisms.

This combination of attributes allows for the development of powerful analytical techniques to visualize and quantify specific types of DNA damage in cells and organisms exposed
