Questions and Answers
Explain the process of genetic engineering in detail.
Genetic engineering involves removing a gene with the desired characteristic from one organism and transferring it into another organism using a vector, resulting in recombinant DNA. The modified organism is then known as a transgenic organism or genetically modified organism (GMO).
What is recombinant DNA (rDNA)?
Recombinant DNA (rDNA) is the DNA that has been altered by the process of genetic engineering, containing lengths of nucleotides from two different organisms, typically from different species.
What is a transgenic organism?
A transgenic organism is an organism that expresses a new gene or genes as a result of genetic engineering.

Study Notes
Genetic Engineering Process
- Genetic engineering involves the manipulation of an organism's DNA to introduce new traits or characteristics
- This process involves the use of biotechnology to alter the genetic makeup of an organism
- Genetic engineering involves the insertion of a gene from one organism into the DNA of another organism
Recombinant DNA (rDNA)
- Recombinant DNA (rDNA) is a molecule of DNA that is created in the laboratory by combining DNA from two or more different sources
- rDNA is formed by cutting and pasting genes from different organisms using restriction enzymes and ligase
- Recombinant DNA is used to introduce new traits into an organism
Transgenic Organisms
- A transgenic organism is an organism that has been genetically engineered to contain genes from another organism
- Transgenic organisms are created by introducing rDNA into the host organism's genome
- Examples of transgenic organisms include bacteria, plants, and animals
Essential Steps for Genetic Engineering
- Isolation of DNA: extracting DNA from the donor organism
- Cutting of DNA: using restriction enzymes to cut the DNA at specific points
- Ligation: using ligase to join the cut DNA with a plasmid or vector
- Transformation: introducing the rDNA into the host organism
- Selection: selecting the transformed cells that have taken up the rDNA
- Verification: confirming the presence of the new gene or trait in the host organism
Genetically Modified Organisms (GMOs)
- A GMO is an organism whose genetic material has been altered using genetic engineering
- GMOs are created to introduce new traits or characteristics, such as resistance to pests or diseases
- GMOs can be used in agriculture, medicine, and other industries
- GMOs can have improved nutritional content, increased yield, or enhanced tolerance to environmental stresses
