Principles of Biotechnology
Among many, the two fundamental techniques that contributed to the development of modern biotechnology are :
- Genetic engineering: This technique is used to modify the chemistry of genetic material (DNA and RNA), insert it into host organisms, and consequently alter the phenotypic of the host organism.
- Preservation of sterile (microbial contamination-free) environment during chemical engineering processes to allow large-scale growth of only suitable microbe/eukaryotic cells for the production of biotechnological products such as antibiotics, vaccines, enzymes, etc.
The following are the main methods used in genetic engineering:
- The donor organism’s DNA fragment is extracted.
- It is put into the DNA of the vector.
- It is subsequently transmitted to the proper host.
- Cloning of the host organism’s recombinant DNA.
