Figure 1From: Telomere and ribosomal DNA repeats are chromosomal targets of the bloom syndrome DNA helicaseAnalysis of rDNA and telomere repeats in normal and BS lymphoblastoid cell lines. A. Diagram of experimental design [28]. B. Relative amounts of total rDNA and telomere DNA in the clones from the normal (HG1522) and BS (HG1525) cell lines using a Perkin-Elmer (ABI) kit for rDNA or rRNA and membrane-transfer hybridization of total genomic DNA for telomere DNA.Back to article page
