Northern blot analysis is performed on cellular mrna isolated from e. coli. the probe used in the northern blot analysis hybridizes to a portion of the lacy sequence. above is an example of the autoradiograph from northern blot analysis for a wild-type lac+ bacterial strain. in this gel, lane 1 is from bacteria grown in a medium containing only glucose (minimal medium). lane 2 is from bacteria in a medium containing only lactose. determine the appearance for northern blots of the bacteria listed below. in each case, lane 1 is for mrna isolated after growth in a glucose-containing (minimal) medium, and lane 2 is for mrna isolated after growth in a lactose-only medium. a. lac+ bacteria with the genotype i+p+ocz+y+b. lac- bacteria with the genotype i+p+o+z-y+c. lac- bacteria with the genotype i+p-ocz+y+d. lac+ bacteria with the genotype i-p+ocz+y+e. lac- bacteria with the genotype i+p+ocz-y-
