Key Area 5 - Genetic Engineering Flashcards
What is genetic engineering?
The transfer of genetic information from one cell to another naturally or artificially.
How can people with Type 1 diabetes be treated with genetic engineering?
By transferring the gene for making human insulin into bacterial cells so that they produce the insulin.
What is used to combine the desired gene and the DNA of another species?
Enzymes.
Why are bacterial cells the common recipients of the inserted genes?
The reproduce very quickly, which results quickly in many transformed bacterial cells.
What is the transferred cell called?
A genetically modified organism
How is the required gene inserted into a host cell?
Using plasmids or another vector(carrier)
Give an example of a GM organism
Tomatoes with a longer shelf life.
Give an example of products from GM organisms
Insulin (produced by bacteria)
What are the stages of genetic engineering?
Bacterial plasmid is cut open, then a gene is cut out of a human chromosome. The gene is inserted into the plasmid. The plasmid is inserted into the bacterial cell wall with a DNA strand.
