E) radioactive eukaryotic cells.

Question

Quizplus · Accepted Answer

BACs (bacterial artificial chromosomes) are widely used for constructing genomic libraries, as they allow for the stable maintenance of large DNA fragments in bacterial cells. This makes them a good choice for storage and access to the genomic information contained within the library. Recombinant viral RNA, individual wells, DNA-RNA hybrids, and radioactive eukaryotic cells are not commonly used for this purpose.
