A fragment of bacteriophage lambda DNA produced by the restriction endonuclease Eco RI and extending from the immunity region to a point inside gene O is found to have a fully functional origin of replication. Seven ori- mutations of lambda cluster in a small region just to the left of the Eco RI cleavage site which defines the right end of this fragment. These mutations lie within gene O.
