Genetic Engineering Basics

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.
