How does the metagenomics approach help to identify novel genes present in the environment? Explain the process. |
|
Answer» The collective DNA(from various environmental niche) is subjected to restriction digestion using restriction endonucleases and the fragments are cloned into suitable vectors. The clones are then screened for presence of a variety of molecules. The clones expressing novel molecules or molecules with improved characteristics are used for large-scale production by fermentation techniques. |
