pubmed:abstractText |
Telomeric sequences of eukaryotes consist of short tandem repeats organized in arrays of variable length in which the guanine-rich strand runs 5'----3' toward the chromosomal end. The terminal repeats in yeast are the only elements necessary for telomere function in this organism. To test whether mammalian terminal repeats can function after reintroduction into a mammalian cell, a repeat-containing terminal fragment from a human chromosome was electroporated into a hamster-human hybrid cell line. In 6 of 27 independent transformants analyzed, the introduced sequences were found at the ends of chromosomes, based on all available criteria. Terminal restriction-fragment heterogeneity and the survival of these chromosomes demonstrate that these telomeres are functional. Cytogenetic evidence from one of these cell lines suggests that chromosome breakage with healing at the integration site is the mechanism responsible for the terminal location.
