A) a list of human genes whose functions have been identified and that have been mapped to a chromosomal locus.
B) a list of human genes, including SNPs and mutations.

E) a set of DNA probes corresponding to a genome.

Question

Quizplus · Accepted Answer

A genomic library is a collection of recombinant DNA clones that collectively represent the entire genome of an organism. These clones are usually propagated in bacterial or viral vectors, and each clone typically carries a randomly selected piece of the genome. Therefore, choice C is the best answer as it describes a collection of recombinant bacteria that contain multiple copies of the genome. The other choices, though related to genetics or genomics, do not accurately reflect the nature of a genomic library.
