| Eighteen candidate clones from the genomic library were digested with a series of restriction enzymes, Southern blotted, and hybridized with the same probe. |
| All constructs were verified by restriction enzymes analyses and sequencing. |
| A person must interfere in the process to obtain the required sequences of actions through many restriction enzymes. |
| The binding mechanism of psoralens to a double-strand DNA has been well investigated by chemical and enzymatic methods using restriction enzymes and exonuclease. |
| Using proteins called restriction enzymes, individual genes from human DNA or genetically engineered in the laboratory, are isolated and inserted into small circular pieces of DNA, known as plasmids. |
| Double-stranded oligos were multimerized using T4 DNA ligase in the presence of XhoI and SalI restriction enzymes to generate tandem arrays. |
