Expert Answer
Biotechnology deals with the techniques of using live microorganisms, plant or animal cells or their components or enzymes from organisms to produce products and processes useful to human beings.
Principles of Biotechnology:
- The techniques of genetic engineering include the creation of recombinant DNA, use of gene cloning and gene transfer.
- Recombinant DNA is the hybrid DNA from two different sources, from by the union of foreign DNA and vector DNA.
- A specific DNA sequence called the ‘ori site’ or ‘origin of replication’ in a chromosome is responsible for the initiation of replication.
- A foreign DNA linked with the origin of replication can replicate and multiply itself in the host organism. This process is called cloning, i.e. forming multiple identical copies of any template DNA.
