Host specificity of DNA produced by escherichia coli. II. Control over acceptance of DNA from infecting phage lambda.

Order of authorship in the original publication: Dussoix, Arber. The authors discovered that restriction of DNA from infecting bacteriophage was due to the attack and breakdown of the modified bacteriophage's DNA by specific enzymes of the recipient bacteria. This was a key development in understanding the restriction modification system (RM system).
