barI and barII siles and their nucleotidc sequences in the lambda genome. The double line (top) represents Ihe complete lambda. genome. The
first enlargent (middle) shows the genetic context surrounding bari and barII loci The second enlargement (bottom) shows the homologous
sequence in barI and BarII, Nucleotides forming part of the open reading frames of barl and barll are indicated by arrows, b. Sequences of barI
barII transcrirrs, Underlined nucleotides are the S-D seqnences and those in boldface indicate the putative ORFs of bar minigenes.
