3. Read the text and check your ideas to exercises 1 and 2.
There are numerous applications of biotechnology: it has been a part of the agricultural industry for quite some time. In addition to the agricultural uses, biotechnology has also been making waves in the pharmaceutical industry. Red biotechnology brings together all those biotechnology uses connected to medicine. Red biotechnology includes producing vaccines and antibiotics, developing new drugs, molecular diagnostics techniques, regenerative therapies and the development of genetic engineering to cure diseases through genetic manipulation. Some relevant examples of red biotechnology are cell therapy and regenerative medicine, gene therapy and medicines based on biological molecules such as therapeutic antibodies.
When you hear the term red biotechnology applications, you may not know what it is referring to, but in the medical industry it refers to biopharmaceutical, which is defined as medical drugs that are produced by applying methods of biotechnology.
Some of the biopharmaceuticals that are produced through the use of biotechnology include antibodies, nucleic acids, proteins, DNA and RNA. These are all used for in-vivo therapeutic or diagnostic purposes. They are different than other pharmaceuticals because they are developed using methods of biotechnology rather than direct extraction.
43
The first biopharmaceutical that was approved for use is actually insulin. Insulin was created using recombinant technology with DNA. Since the inception of insulin being released and used in the medical community, there have been continuous strides in the field of biopharmaceuticals. Most of these are derived from forms of living organisms.
Once a biopharmaceutical is created and approved for use, it typically goes through the process of being patented to give it exclusive rights for manufacturing and production. Because of the high cost usually associated with using biotechnology methods in creating biopharmaceuticals, it is important to the creator of the new drug to be able to maintain rights to it to help absorb a portion of the cost it took in the stages of development.

1 What applications does red biotechnology include?
2 What are cell therapy and regenerative medicine based on? 3 Why do biopharmaceuticals differ from others?
4 What was the first biopharmaceutical?
5 What process does a biopharmaceutical go through typically?
