M-MuLV-induced leukemogenesis: integration and structure of recombinant proviruses in tumors.

abstract：:Chromatin assembly factor 1 (CAF-1) and Rtt106 participate in the deposition of newly synthesized histones onto replicating DNA to form nucleosomes. This process is critical for the maintenance of genome stability and inheritance of functionally specialized chromatin structures in proliferating cells. However, the mol...
