YAC cloning of telomeres.
Human telomeres have been successfully cloned in Saccharomyces cerevisiae by complementing deficient yeast artificial chromosomes (YACs). This technique allows cloning of DNA sequences that can recognize particular chromosomal ends, and therefore facilitates the mapping of eukaryotic genomes. Although the biology of adopting foreign telomeres in yeast is not fully understood, the cloning system itself seems to be a useful tool for constructing telomeric DNA libraries from higher eukaryotes. Here we describe the techniques that are currently being used in cloning of telomeric DNA.
