Question

What is the advantage of a genomic library?

Answer 1

1. Complete representation: Genomic libraries contain the entire genome of an organism, including both coding (exons) and non-coding (introns, regulatory) sequences.
2. Source of all genes: They provide a source for all the genes of an organism, useful for gene cloning and study.
3. Preservation of gene organisation: They maintain the original arrangement of genes and regulatory elements as in the genome.
4. Useful for studying gene structure and function: Because introns and regulatory regions are included, genomic libraries help study gene regulation and expression.
5. Resource for physical mapping: They aid in physical mapping of chromosomes and in genome sequencing projects.
6. Use in transgenic studies: Genes along with their regulatory elements can be cloned for transgenic organism creation.
