Disruption of the c/ebp alpha gene in adult mouse liver.

abstract：:Eukaryotic chromosomes are organized into domains of activity for both transcription and DNA replication. Transcriptional "border," or "insulator," elements have been implicated in mediating the organization of transcriptional domains. However, the DNA sequence elements which might demarcate domains of DNA replication...

abstract：:Unlike other eukaryotes, the protein-coding genes of Trypanosoma cruzi are arranged in large polycistronic gene clusters transcribed by polymerase II (Pol II). Thus, it is thought that trypanosomes rely solely on posttranscriptional processes to regulate gene expression. Here, we show that the glucosylated thymine DNA...
