- Recombinant DNA (human gene and Bacterial Plasmid)
- transfer this structure to the host cell (virus)
- inside the virus - nucleic acid (e.g. DNA or RNA)
- around the virus - protein shell (capsid)
- first thing - remove the nucleic acid from the virus to leave the capsid
- The plasmids are taken up by the virus. The virus acts as a vector for the recombinant DNA
- This helps to transfer the DNA into the host cell
- This virus is known as a phage (infects bacterial cells)
- able to attach to the cell membrane of the bacteria and insert the recombinant DNA into the host cell
- at the end of the process: Bacterial cell which contains the recombinant DNA (including the human gene, insulin)
- The bacteria has its own DNA plus the DNA from another organism - this combination is known as 'transgenic'
