DNA from a strain of Bacillus subtilis with genotype a+b+ c+d+ e+ is used to transform a strain with genotype a - b- c- d-   e-. Pairs of genes are checked for co-transformation and the following results are obtained:

Pair of co-transform genes as follow

D-E,             E-C,                C-B,                  A-D

On the basis of these results, what is the order of the genes on the bacterial chromosome?
