FAQs on Transgenes and Transgenic Organisms Video Lecture - Science & Technology for UPSC CSE

1. What are transgenes and transgenic organisms?
Ans. Transgenes are genes that have been artificially introduced into an organism's genome, whereas transgenic organisms are those that have had foreign genes inserted into their DNA through genetic engineering techniques.
2. How are transgenes inserted into organisms?
Ans. Transgenes can be inserted into organisms using various methods, such as microinjection, electroporation, and gene gun. These techniques allow scientists to directly introduce foreign DNA into the cells of an organism.
3. What are the applications of transgenic organisms?
Ans. Transgenic organisms have various applications in agriculture, medicine, and research. They can be used to develop crops with enhanced traits, such as disease resistance or increased yield. In medicine, transgenic organisms are used to produce therapeutic proteins or study the effects of specific genes on diseases.
4. Are there any potential risks associated with transgenic organisms?
Ans. While transgenic organisms offer numerous benefits, there are also potential risks. These include unintended ecological consequences, such as the spread of transgenes to non-target species, and the potential for allergenic or toxic effects from the expressed transgenes.
5. What is the controversy surrounding transgenic organisms?
Ans. The use of transgenic organisms is a topic of debate and controversy. Some concerns raised include the potential for genetic pollution, ethical considerations regarding the manipulation of living organisms, and the effect of genetically modified crops on biodiversity and human health.
