Study Notes
Genetic Engineering Overview
- Genetic engineering involves the deliberate modification of an organism's DNA.
- This biotechnological process allows for the alteration of genetic material to achieve desirable traits or characteristics.
Steps of Genetic Engineering
- Isolation: Extracting the gene of interest from the organism.
- Cutting: Using restriction enzymes to cut both the isolated gene and the target DNA at specific sites.
- Ligation: Joining the DNA fragment of interest with the target DNA using ligase enzymes.
- Transformation: Introducing the new DNA into a host organism, such as bacteria, plants, or animals.
- Cloning: Replicating the transformed organism to produce multiple copies containing the desired gene.
- Expression: Activating the inserted gene to produce the intended protein or trait.
Applications in Plants
- Certain crop plants have been genetically modified to incorporate a bacterial gene for herbicide resistance, allowing them to survive applications of weed killers.
Applications in Animals
- Genetic engineering enables the insertion of a human gene into sheep DNA, facilitating the production of therapeutic proteins in sheep's milk, which can be utilized for treating conditions such as emphysema.
Applications in Micro-organisms
- The gene coding for human insulin can be inserted into bacteria, resulting in the bacteria producing significant quantities of insulin for medical use, addressing diabetes treatment needs.
