The following is a schematic representation of region of the chromosome of fly along with extent of six deletions (Del 1 to Del 6); 

When flies homozygous for the recessive mutations are crossed with flies heterozygous for the deletions, the following results are obtained, in which "m" represents a mutant phenotype and a plus sign (+) represents the wild type. On the basis of these data, determine the relative order of the seven mutant eenes on the chromosome.

The sequence of σ54 is distinctly different from that of all the σ70-like factors, some characteristics about σ54 is given below;

a) The σ54-RNA polymerase binds to the glnA promoter and immediately melt the DNA strands and initiate transcription

b) σ54-polymerase does not require ATP hydrolysis to separate the strands at a start site only require activator such as   NtrC

c) σ54-RNA polymerase initiate transcription of glnA promoter only when it is activated by NtrC

d) ATP hydrolysis is required for activation of bound σ54-RNA polymerase by phosphorylated NtrC
