Genetic Engineering. The simple addition, deletion, or manipulation of a single trait in an organism to create a desired change. Genetic Engineering. The altered DNA is called recombinant DNA Recombinant DNA is joined to other unrelated DNA in the organism This is called gene splicing.
The simple addition, deletion, or manipulation of a single trait in an organism to create a desired change.
- tiny segments of a gene are taken out and replaced by different genes
-moving a gene from one organism to another.
A piece of DNA is removed from the donor organism
A bacterial plasmid is used to carry the DNA
A new gene is joined to the plasmid using DNA ligase
The recombinant plasmid is inserted into a bacterial cell
The plasmid is isolated from the bacteria and the human DNA is cut by the restriction enzyme
Genetic engineering can to produce very specific and sensitive diagnostic tests for many diseases, using engineered proteins.
This new technology is also opening up novel ways of delivering medicines to specific targets.
- Weeds die but the crops survive
- The gene which produces vitamin A was taken from daffodils and put into rice to help prevent blindness
