..The large duplications carried by these cryptic lysogens are stable, unlike tandem duplications, and so may significantly influence the cell's evolutionary potential. ..

..We used T1 RNase mapping to confirm that the putative readthrough RNA made in the presence of 82 Q protein is in fact an elongation product of the shorter RNA. ..

..The enhancing region has 15-bp inverted repeats. These sequences are conserved in the corresponding region of bacteriophage phi 80, which has the same packaging specificity as lambda. ..

..That the qsr' prophage appears not to carry a full complement of essential late genes suggests one explanation for its apparently defective nature. ..

..Small deletions (7 and 11 bp) between cosN and cosB abolish packaging in vivo without affecting cos binding and cleavage in vitro, whereas a large deletion (26 bp) abolishes packaging in vivo and cleavage in vitro. ..
