Welcome, class! Today we're diving into biotechnology. It's essentially the use of biological systems to create or modify products. The European Federation of Biotechnology defines it as the integration of natural sciences with living organisms. Why do you think this is important?
Because it helps in improving health and food production!
And it can also be used for environmental purposes.
Absolutely! Biotechnology plays a role in various fields including agriculture, medicine, industry, and environmental science.

Let's talk about two core techniques: genetic engineering and bioprocess engineering. Genetic engineering allows us to manipulate DNA. Can anyone give me an example of this?
Like creating GMO crops?
Or producing insulin using bacteria?
Exactly! Now, bioprocess engineering is all about creating optimal conditions to produce these products. Can anyone remember what products we might manufacture?
Enzymes and vaccines!

Now, let's expand on the applications of biotechnology. In agriculture, we use genetically modified crops to enhance yield, resistance, and nutritional quality. What are examples you've learned about?
Bt Cotton and Golden Rice!
What about biofertilizers? I think Rhizobium is an example!
Correct! And in medicine, we have advancements like genetically engineered insulin. Why is it better than what we had before?
Itโs more compatible with our bodies!

Finally, letโs address the bioethics and biosafety concerns in biotechnology. Why do you think these are important?
Because we need to ensure that the modifications donโt harm humans or the environment!
I remember hearing about allergies related to GMOs.
Exactly. We must balance the benefits with potential risks.

According to the European Federation of Biotechnology (EFB):
"Biotechnology is the integration of natural science and organisms, cells, parts thereof, and molecular analogues for products and services."
In simpler terms, biotechnology involves using living organisms or systems to make products that benefit humans.
Detailed Explanation
Biotechnology merges natural sciences like biology, chemistry, and physics with living organisms. It focuses on manipulating cells or their biological components to create useful products, such as medicines and crops. The EFB emphasizes the integration of various sciences in this process, indicating that biotechnology relies on a diverse set of knowledge to innovate and solve problems.
Examples & Analogies
Think of biotechnology like cooking. Just as a chef uses different ingredients (cells, organisms) and techniques (science, engineering) to create a dish (product), biotechnologists combine various scientific disciplines to produce beneficial items, such as insulin for diabetics.
