Question

Give reason: All the fragments of a genome are cloned for storing them in genomic library.

Answer 1

1. When producing a genomic library, genomic DNA is fragmented.
2. It is unclear which piece contains the requested gene.
3.  As a result, all of the fragments must be cloned in order to store the copies of each independently.
4. The desired gene is then screened for using complementation or DNA probes.
5. As a result, all genome fragments are cloned and stored in a genomic library.
