A genetic analysis of the 63E-64A genomic region of Drosophila melanogaster: identification of mutations in a replication factor C subunit.

abstract：:The RecQ helicase family is critical during DNA damage repair, and mutations in these proteins are associated with Bloom, Werner, or Rothmund-Thompson syndromes in humans, leading to cancer predisposition and/or premature aging. In the budding yeast Saccharomyces cerevisiae, mutations in the RecQ homolog, SGS1, phenoc...
