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.
