Abstract excerpt

BACKGROUND: chi sequence (5'GCTGGTGG) of Escherichia coli was first identified as a site that increased the plaque size of bacteriophage lambda. Subsequent studies showed that this site is responsible for both the attenuation ofRecBCD exonuclease activity and the promotion of RecA, RecBCD-mediated recombination. It is known that bacteriophage lambda containing the chi site makes very small plaques on a recC*...
