c) There are multiple methods - the main one uses molecular cloning to amplify fragments of genomes for further study and addition to a collection
What are genomic libraries ?
A genomic library is a comprehensive collection of cloned DNA snippets that make up an organism's whole genome .
Methods such as shot gun experiment is used , in which the entire genome of the is cloned in a random sequence .Construction of a genomic library involves the isolation of genomic DNA, purification of the genomic DNA and fragmentation of genomic DNA into desired size , then cloning of the fragmented DNA using a suitable vector .
Hence , genomic libraries are created by different methods .
