Study Notes
Genetic Engineering
- Involves techniques to modify the chemistry of DNA and RNA.
- Allows for the introduction of engineered genetic material into host organisms, resulting in altered phenotypes.
Bioprocess Engineering
- Ensures a sterile environment for cultivating specific microbes or eukaryotic cells.
- Facilitates large-scale production of antibiotics, vaccines, enzymes, and other bioproducts.
History of Recombinant DNA Technology
- The first recombinant DNA was developed by Stanley Cohen and Herbert Boyer in 1972.
- They successfully linked an antibiotic resistance gene with a plasmid from Salmonella typhimurium.
Steps in Genetically Modifying an Organism
- Identification of DNA: Locate DNA containing desirable genes.
- Introduction of DNA: Insert the identified DNA into the chosen host organism.
- Maintenance and Transfer: Ensure the introduced DNA is maintained in the host and can be passed to its descendants.
Tools of Recombinant DNA Technology
- Desired DNA: The target genetic material to be inserted.
- Restriction Enzymes: Enzymes that cut DNA at specific sequences, invaluable for gene manipulation.
- DNA Polymerase: Enzyme that synthesizes DNA strands, crucial for DNA replication.
- Ligases: Enzymes that join together DNA fragments.
- Vector: A vehicle used to transfer foreign genetic material into a host cell.
- Host Cell/Organism: The living entity that receives the recombinant DNA.
