Bacteria and other microbes can be used to " clean up" an oil spill by breaking down oil into carbon dioxide and water.two samples isolated from the deepwater horizon leak in the gulf of mexico were labeled a and b.the dna of each was isolated and the percent thymine measured in each sample.assume the organisms contain normal double-stranded dna and predict the composition of the other bases.
-sample a contains 21.1% thymine
%a
-sample b contains 27.1% thymine
%a
-number
%g

%g

%c

%c
both samples are then denatured to remove the secondary structure.which will have the higher temperature to denature a or b ?

In sample A,  

As A comprises 21.1% thymine, so A = T = 21.1%

Also, A+T = 42.2%

Therefore, G+C = 57.8%

So, G = 57.8/2 = 28.9%

Also, G = C = 28.9%

In sample B,  

Sample B comprises 27.1 % thymine, therefore A = T = 27.1%

Also, A+T = 54.2%

Thus, G+C = 45.8%

So, G = 45.8/2 = 22.9%

Also, G = C = 22.9%

Since, the content of GC is more in the sample A, that is, 57.8 %. Thus, the sample A exhibits higher temperature to denature in comparison to B, which is 45.8%.
