The dynamics of DNA damage repair and transcription.

Recent advances have led to several systems to study transcription from defined loci in living cells. It has now become possible to address long-standing questions regarding the interplay between the processes of DNA damage repair and transcription-two disparate processes that can occur on the same stretch of chromatin and which both lead to extensive chromatin change. Here we describe the development of a system to create enzymatically induced DNA double-strand breaks (DSBs) at a site of inducible transcription and methods to study the interplay between these processes.
