Genetic Engineering Flashcards
What is a plasmid
A ring of dna found in the bacterial cell
What is genetic engineering
The artificial transference of plasmids in cells
What is genetic transfer
The natural transfer of plasmids in cells
1st step of genetic engineering
Identify section of dna that contains required gene from source chromosome
2nd step
An enzyme is used to extract the required gene
3rd
A plasmid is removed from a bacterial cell and is cut open using an enzyme
4th step
A different enzyme is used to insert and seal the gene into the bacterial plasmid
Final step
The altered plasmid is inserted into a host bacterial celll and given the optimum conditions to multiply. Each bacterium produced has been modified
Two useful products of genetic engineering
Insulin, hormones
