Biotechnology MCQ FAQs
What is biotechnology?
Biotechnology is a field of science that uses living organisms, cells, and biological systems to develop or create products for medical, agricultural, industrial, and environmental purposes. It combines biological research with technological applications to solve problems and improve life.
What are the types of biotechnology?
There are four main types of biotechnology:
Red Biotechnology: Related to medical applications, such as developing drugs, vaccines, and gene therapies.
Green Biotechnology: Focuses on agriculture, improving crops, pest-resistant plants, and sustainable farming practices.
White Biotechnology: Also known as industrial biotechnology, it involves using biological processes to manufacture biofuels, bioplastics, and other chemicals.
Blue Biotechnology: Concerns marine and aquatic organisms, with applications in biofarming, pharmaceuticals, and environmental conservation.
How is biotechnology used in medicine?
Biotechnology is used in medicine for the production of vaccines, antibiotics, and insulin. It also plays a role in gene therapy, where defective genes are replaced or repaired to treat genetic diseases. Biotechnology also supports the development of diagnostic tools and treatments for various medical conditions
What are GMOs?
GMOs (Genetically Modified Organisms) are organisms whose genetic material has been altered in a way that does not occur naturally. This can involve inserting new genes or modifying existing ones to improve traits such as disease resistance, faster growth, or higher nutritional value.
How does biotechnology help in agriculture?
In agriculture, biotechnology is used to develop crops that are resistant to pests, diseases, or environmental stress. It can also enhance the nutritional value of crops and reduce the need for chemical pesticides. This technology helps improve food security by increasing crop yields and reducing the environmental impact of farming.
What is genetic engineering?
Genetic engineering is the manipulation of an organism's DNA to achieve desired traits. This can involve adding, removing, or altering specific genes. Genetic engineering is used in biotechnology for purposes such as producing genetically modified crops, creating medicines like insulin, and developing gene therapies for diseases.
What is gene therapy?
Gene therapy is a medical treatment that involves altering the genes inside a person’s cells to treat or prevent disease. The goal is to replace or repair faulty genes that cause diseases, such as cystic fibrosis, hemophilia, or certain types of cancer. Gene therapy is still being researched and developed.
What is PCR (Polymerase Chain Reaction)?
PCR is a laboratory technique used to amplify or make many copies of a specific segment of DNA. This allows scientists to study small amounts of DNA more easily. PCR is widely used in genetic testing, diagnostics, forensic science, and research.
