Keep the sequence straight

Digest DNA with restriction enzymes, separate fragments by gel electrophoresis, isolate the gene of interest, ligate it into a vector, introduce recombinant DNA into host cells, select recombinants, and culture them in a bioreactor. Cohen’s early contribution included plasmid transfer between bacteria.

  • ✓Cut → separate → isolate → ligate → transfer → select → scale up.
  • ✓Cohen developed a plasmid-transfer method.
OlympIQ trap

Do not place bioreactor culture before recombinant selection.
