4. What Are Genetically Modified Organisms (GMOs)?

Genetically Modified Organisms (GMOs) are organisms whose genetic material has been altered using biotechnology techniques like genetic engineering. This modification is intended to give the organism new traits, such as disease resistance, improved nutritional content, or tolerance to environmental stress. GMOs are common in agriculture for producing crops that yield more or require fewer pesticides. In medicine, GMOs are used to produce drugs and vaccines. While GMOs offer benefits, they also raise ethical, environmental, and safety concerns, leading to regulatory scrutiny worldwide.

5. What Are The Applications Of Biotechnology In Medicine?

In medicine, biotechnology is applied to develop vaccines, antibiotics, gene therapy, and personalized medicine. It enables the production of recombinant proteins like insulin and growth hormones. Biotechnology also aids in diagnosing diseases through molecular diagnostics and developing targeted cancer treatments. Advances such as CRISPR gene editing allow correction of genetic disorders. Overall, biotechnology improves healthcare by offering innovative treatment options, enhancing disease prevention, and enabling more precise diagnostics.

6. How Is Biotechnology Used In Agriculture?

Biotechnology in agriculture focuses on improving crop yield, resistance to pests and diseases, and tolerance to environmental stresses such as drought. It involves creating genetically modified crops with enhanced nutritional content or longer shelf life. Biotechnology also helps develop biofertilizers and biopesticides that are environmentally friendly. These advances contribute to sustainable farming, reducing chemical use and improving food security.

7. What Are The Ethical Concerns Associated With Biotechnology?

Ethical concerns in biotechnology include the safety and long-term effects of genetically modified organisms, potential environmental impacts, and issues related to gene editing, especially in humans.
