Fluorescence in situ hybridization with a synthetic (T2AG3)n polynucleotide detects several intrachromosomal telomere-like repeats on human chromosomes.

(T2AG3) repeats comprise the telomeres of human chromosomes and also are present at interstitial locations. Using a long synthetic (T2AG3)n probe, we have localized telomere-like repeats at several internal sites on human chromosomes.
