While Shelly was away from the lab, Rene decided that it would be easier to divide the lengthy segment into smaller pieces, or subclones, and to insert each fraction into plasmids, little circles of DNA and protein.

(1) from the genomic library a clone of interest is selected and a small fragment is subcloned from one end of the clone
