30. The term "whole-genome shotgun sequencing" refers to: (A) A strategy to sequence an entire genome by breaking up DNA and sequencing using oligonucleotide primers that span the genomic DNA.. (B) A strategy to sequence an entire genome by breaking up DNA, cloning it into libraries, and sequencing using oligonucleotide primers that correspond to know chromosomal locations (contigs). (C) A strategy to sequence an entire genome by breaking up DNA, cloning it into libraries, hybridizing small fragments, then reassembling the fragments into a complete map. (D) A strategy to sequence an entire genome by breaking up DNA, cloning it into libraries, sequencing small fragments, then reassembling the fragments into a complete map.
