A) a collection of literature about DNA
B) a collection of organisms for extracting DNA
C) packing of donor DNA in a collection of vectors
D) a collection of gene vectors
Correct Answer: C
Solution :
Genomic library is a collection of all the DNA fragments of a particular genome, with each fragment attached to a cloning vector and maintaining the cloning vectors in culture media indefinitely. Cloning vectors can be plasmids, cosmids or bacteriophages. A genomic library is constructed generally by applying the Shotgun sequencing. The bacterium like Escherichia coli is used to maintain the gene library. The healthy gene from gene library can be picked up whenever required and used variously in gene therapy and production of desired chemicals.
