Recombinant DNA Flashcards
1
Q
what is recombinant DNA
A
when DNA from one organism is inserted into the DNA of another organism
2
Q
how are restriction enzymes used
A
theyre used to cut out a gene of interest and cut open the host DNA where the gene will be inserted
3
Q
how is DNA ligase used
A
used to glue the fragment inside
4
Q
uses of recombinant DNA (4)
A
1) makes it easier for scientists to study genes in the lab
2) use bacteria to produce hormones and enzymes for medical use (ex: insulin, growth hormone)
3) use viral genes in host cell to create antigens for vaccines
4) creating transgenic organisms (GMO’s)
5
Q
3 examples of GMO’s
A
- insect-resistant corn
- glofish
- cold-tolerant tomatoes
