Module B7: Future Biology

Here they learn more about the science behind this application, and also other new genetic technologies, including genetic modification and large-scale growth of microorganisms to produce, for example, antibiotics, single-cell protein and hormones. They also consider the economic, social and ethical implications for the release of genetically modified organisms.

Section B7.4: New Technologies

3. Recall the main steps in genetic modification as:

• isolating and replicating the required gene;
• transferring the gene into a new cell;
• use of a vector (virus or plasmid);

4. Recall that genetic modification includes:

• bacterial synthesis of drugs and hormones, for example, insulin;
• disease resistance in crop plants;

5. Understand that there are economic, social and ethical implications for the release of genetically modified organisms.
