Deletion of DDB1 in mouse brain and lens leads to p53-dependent elimination of proliferating cells.

abstract：:Telomerase activity was demonstrated in cell-free extracts from S. cerevisiae through the use of a PCR-based assay. As expected, this activity was eliminated by RNase or phenol treatment of the extract and was dependent on dGTP and dTTP. Telomerase was not detected in extracts prepared from cells grown for approximate...
