Dynamic rearrangements of TAS in survivors of senescence. (A) Genomic DNA (15 μg) was prepared from trt1− and pku70− trt1− cultures on the indicated days, digested with NsiI, and fractionated on agarose gels. DNA was transferred onto a nylon membrane and hybridized to a 32P-labeled TAS1 probe. Size markers are as in Figure 2. (B) The blot shown in A was stripped as described in MATERIALS AND METHODS and hybridized to a TAS3 probe.
