Genetic Engineering Flashcards

Q
Give an example of genetic engineering naturally
A
Viruses inserting genes into the and DNA of a host cell
Bacteria pass genes naturally from one to another in plasmids
1
Q
What is genetic engineering ?
A
When genetic information can be transferred from one cell to another, this can also happen naturally
2
Q
What are viruses and plasmids also knows as?
A
Vectors when they introduce new genes into cells
3
Q
How do humans use vectors ??
A
To transfer genes from one species to another
4
Q
What is useful about genetically modified organisms ?
A
Disease resistance and a valuable product is insulin
5
Q
Describe the process of genetic information:
A
- Identify the required gene in the source chromosome
- The gene is cut out using an enzyme
- The gene is inserted into a bacterial plasmid
- Cells from the host species take up the plasmid containing the required gene and make the product
- The modified bacteria or fungi are multiplied and the product is harvested and purified
- Alternatively, transformed plant or animal cells are grown to produce genetically modified organisms that have a useful characteristic or make a valuable product
