“…Em 1970, Hamilton Smith e Kent W. Wilcox descobriram a primeira enzima de restrição do tipo II, que permitiu o corte de moléculas de DNA em sítios específicos (10), que eram depois separados por eletroforese em gel. Isso permitiu aos cientistas isolar genes de genoma de um organismo (11 (17).…”

“…Much of that work was carried out by the Swiss microbiologist and geneticist Werner Arber and his student Daisy Dussoix, who showed that the DNA of restricted phage is enzymatically degraded (9). In 1970, Hamilton Smith and his colleagues at Johns Hopkins University reported that a restriction enzyme they named HindII-a protein isolated from the bacterial pathogen, Haemophilus influenzae-recognizes particular nucleotide sequences in DNA and cuts duplex DNA site-specifically at these sequences (36). The following year, Karen Danna and Daniel Nathans found that the HindII endonuclease cleaves DNA of the mammalian tumor virus SV40 into 11 fragments that can be separated by acrylamide gel electrophoresis, demonstrating the utility of restriction endonucleases for DNA analysis (37).…”

“…Restriction endonucleases were discovered originally as a bacterial defensive mechanism (restriction-modification system) against the invading phages or plasmid DNA in 1970 [1]. A similar but RNA-based adapted heritable immune system of bacteria was found recently using CRISPR/Cas9 (Clustered Regularly Interspaced Short Palindromic Repeat/CRISPR associated protein 9) [2] [3].…”
