One advantage to using NGS genome assembly over the Sanger method is that ________.
A. NGS involves inserting the genomic fragments into vectors, which is an efficient process compared to using the oligonucleotide adapters employed in the Sanger method B. NGS involves the construction of a genomic library, giving extra depth of coverage compared to the Sanger method C. NGS sequences the same fragment no more than 10 times, avoiding wasteful processes compared to the Sanger method D. NGS avoids the need to insert fragments into cloning vectors, using oligonucleotide adapters that bind to a solid surface instead
