Study Notes
Plant Biotechnology
- Single crops often need to meet multiple requirements, including sustainable food and healthful nutrition, environmental protection, and job opportunities.
- Developing suitable plants is a complex challenge.
Gene Transfer Process
- Involves removing genetic information from an organism, manipulating it in a laboratory, and transferring it into a plant to alter certain characteristics.
- Electrical pulses are applied to a suspension of cells with DNA in an electroporation cuvette placed between electrodes.
Gene Transfer Methods
- Electroporation method: uses electrical pulses to transfer genes.
- Silicon carbide method: uses fibers of organic material like silicon carbide for gene transfer.
Progress in Gene Transfer Technology
- Dramatic progress has been made in the development of a gene transfer system for higher plants in the last few years.
- About 20 crops can be genetically engineered at present.
This quiz explores the multifaceted role of agriculture in providing food, protecting the environment, and creating job opportunities. It delves into the interconnectedness of sustainable agriculture and its impact on the ecosystem.
