Mitotic recombination in Saccharomyces cerevisiae.

abstract：:Cellular reverse transcriptase-related (rvt) genes represent a novel class of reverse transcriptases (RTs), which are only distantly related to RTs of retrotransposons and retroviruses, but, similarly to telomerase RTs, are immobilized in the genome as single-copy genes. They have been preserved by natural selection t...
