Telomeric repeats are indicated by bold letters. Substitutions and insertions are underlined.
The incorporation of a single [32P]dGMP residue into oligos tel1 to tel8 was determined in assays of the type shown in Fig. 2B. A labeled oligonucleotide was added to each sample before the ethanol precipitation step, and the radioactivity recovered in this oligonucleotide was used to correct the data for losses that occurred during the procedure. The data are expressed relative to the incorporation into oligo tel1, which was set at 100. Each assay was repeated three times. Average values and standard deviations are shown here.
