A function for subtelomeric DNA in Saccharomyces cerevisiae.
The subtelomeric DNA sequences from chromosome I of Saccharomyces cerevisiae are shown to be inherently poor substrates for meiotic recombination. On the basis of these results and prior observations that crossovers near telomeres do not promote efficient meiosis I segregation, we suggest that subtelomeric sequences evolved to prevent recombination from occurring where it cannot promote efficient segregation.
