When wild-type (normal) E. coli is grown on medium containing X-gal, the bacterial colonies turn blue. In contrast, when lacZ mutants are grown on medium containing X-gal, the bacterial colonies remain their normal white color. X-gal is likely to be a compound _____.

WebbWe computationally predict operons in the Synechococcus sp. WH8102 genome based on three types of genomic data: intergenic distances, COG gene functions and phylogenetic profiles. In the proposed method, we first estimate a log-likelihood distribution for each type of genomic data, and then fuse these distribution information by a perceptron to … WebbTo test whether yaeB influenced the growth of S.Typhimurium in macrophages, the growth rate of the yaeB mutant strain in RAW264.7 cells was examined. First, deletion of the y ae B gene did not affect bacterial growth in vitro ().However, the growth rate of the yaeB mutant in RAW264.7 cells was reduced 3.0-fold (Figure 1A) compared with that in the wild-type …
