A recently isolated bacterial strain has been given to you for general characterization of the genome.You begin by isolating the DNA and subjecting it to thermal denaturation.You use Escherichia coli (E.coli)DNA as a reference.

A recently isolated bacterial strain has been given to you for general characterization of the genome.You begin by isolating the DNA and subjecting it to thermal denaturation.You use Escherichia coli (E.coli)DNA as a reference. Based on the information in the graph,you can determine that the DNA of the new strain has a high A)G-C content with respect to E.coli. B)pyrimidine content with respect to E.coli. C)A-T content with respect to E.coli. D)purine content,with respect to E.coli. E)histone content with respect to E.coli.
