Faithful copying of the genome is essential for all life on earth. In addition to DNA replication, the genome must also be transcribed. However, a specific DNA sequence can only be engaged in either replication or transcription at any one time. Therefore, there are frequently conflicts between the processes of transcription and replication that have the potential to result in genome instability. Cells have efficient pathways to prevent transcription-replication conflicts. However, these pathways are not well understood. We have recently developed a novel genomic technology that can detect transcription-replication conflicts - this will allow us to discover pathways that the celluses to protect the genome.

基因组的忠实复制对于地球上所有生命都至关重要。除了DNA复制之外，基因组还必须进行转录。然而，特定的DNA序列在任何一次只能参与复制或转录。因此，转录和复制过程之间经常存在冲突，有可能导致基因组不稳定。细胞具有防止转录复制冲突的有效途径。然而，这些途径还没有被很好地理解。我们最近开发了一种新型基因组技术，可以检测转录复制冲突 - 这将使我们能够发现细胞用来保护基因组的途径。
