title: Procaryotic genomic DNA inhibits mammalian cell transformation.
abstract: Ltk- mouse cells were transformed to thymidine kinase prototrophy in the presence of carrier DNAs isolated from different organisms. Procaryotic genomic and phage DNA was consistently less effective as a carrier than was eucaryotic DNA. Mixing experiments indicate that DNA of procaryotic origin inhibits mammalian cell transformation.
