    Approximating the copy number of 16S rDNA in commercial Taq polymerases. Six DNA polymerases were used with primers for 16S rDNA on 7 serial 10-fold dilutions of E. coli genomic DNA (10 ng to 10 fg) with no added DNA in the 8 th sample. The least squares fit equation for each dilution series was used to assign a value to the signal from the 8 th sample, which contains Taq-associated DNA only. The efficiency of the reaction was determined from the slope of the linear fit plotting the base10 log of the DNA concentration vs. the threshold cycle. A slope of −3.322 indicates an average doubling rate of “2,” which is approximately 100% efficiency (2̂3.322∼10). The rDNA values assigned are for “E. coli equivalents.”

    Diagram of the LM-PCR protocol to detect top1-induced DNA single-strand breaks and replication-mediated DNA double-strand breaks. Top1 is shown as a shaded oval with covalent linkage to the 3′ end of a DNA single-strand break. In the assay for top1-induced DNA single-strand breaks, top1-induced DNA single-strand breaks (i.e., top1 cleavage complexes) were detected (upper left) as described previously by annealing primer 1 (P1) to denatured genomic DNA. After primer extension and in vitro phosphorylation of the 5′-OH termini with T4 polynucleotide kinase, ligation to the double-stranded linker was performed. Thereafter, rRNA gene-specific DNA fragments were amplified with Taq DNA polymerase using the linker-primer and a nested, gene-specific PCR primer. After 26 cycles of PCR, a third primer (5′ end labeled with 32 P; star) was used for two primer extension cycles before the samples were separated in 7% denaturing polyacrylamide gels. In the assay for replication-mediated DNA double-strand breaks, collision between a replication fork and a top1 cleavage complex is proposed to lead to replication runoff, with generation of a DNA double-strand break (upper right). Because of in vivo 5′-end phosphorylation of replication-mediated DNA double-strand breaks, ligation to the linker could be performed without prior T4 polynucleotide kinase reaction. The following reaction steps were the same as for the detection of top1-induced DNA single-strand breaks. Note that the single-strand break assay detects both single- and double-strand breaks.

Input represents PCR amplification of 1% of the genomic DNA. Primer pairs P1-P2 and P3-4 correspond to the upstream and the promoter region respectively. P5-P6 corresponds to 3' region of Ccnd2 gene and serves as a negative control. Results shown are a representative of two independent experiments. D . The cyclin D2 promoter is repressed by Elf5 in reporter gene assays in mammary epithelial cells .

    Approximating the copy number of 16S rDNA in commercial Taq polymerases. Six DNA polymerases were used with primers for 16S rDNA on 7 serial 10-fold dilutions of E. coli genomic DNA (10 ng to 10 fg) with no added DNA in the 8 th sample. The least squares fit equation for each dilution series was used to assign a value to the signal from the 8 th sample, which contains Taq-associated DNA only. The efficiency of the reaction was determined from the slope of the linear fit plotting the base10 log of the DNA concentration vs. the threshold cycle. A slope of −3.322 indicates an average doubling rate of “2,” which is approximately 100% efficiency (2̂3.322∼10). The rDNA values assigned are for “E. coli equivalents.”
