| Furthermore, sequencing data and Southern data indicated that no rearrangements of the DNA had occurred, as all internal restriction enzyme sites remained intact producing hybridization fragments of the expected size. |
| The restriction enzyme and its corresponding methylase constitute the restriction-modification system of a bacterial species. |
| Genetic characterisation of ASF virus isolates is achieved by determining restriction enzyme patterns and nucleotide sequences of portions of the virus genome. |
| The PCR-amplified products were confirmed as BHV-1 by restriction enzyme, Dde1, which produced fragments of predictable sizes, namely 340 and 128 base pairs. |
| One restriction enzyme allowed the identification of both minimus species, but also closely related species. |
| Rapid identification of mycobacteria to the species level by polymerase chain reaction and restriction enzyme analysis. |
