Bovine pancreatic deoxyribonuclease is an endonuclease which splits phosphodiester linkages, preferentially adjacent to a pyrimidine nucleotide yielding polynucleotides with free hydroxyl group at the 3" position and phosphate group at the 5" position. The average chain length of a limit digest is a tetranucleotide.
