1. Stanley N. Cohen, along with Herbert Boyer, created the first recombinant DNA molecules in the early 1970s.
2. Cohen's work led to the development of plasmid vectors that could be used to clone foreign genes in bacterial cells.
3. The technique developed by Cohen and Boyer involved using restriction enzymes to cut DNA and ligase enzymes to paste it together.
4. Cohen's research laid the groundwork for modern genetic engineering, including gene therapy and biotechnology applications.
5. One of their key experiments involved inserting antibiotic resistance genes into plasmids, which could then be introduced into E. coli bacteria.
