When DNA is heated, the double strands unwind and separate into single

When DNA is heated, the double strands unwind and separate into single strands due to the breaking of hydrogen bonds between the bases. This process is called denaturation. An experiment was performed where two molecules of DNA were placed in a solution and heated. Both sets of DNA contained 40 base pairs, but each DNA molecule was modified such that one DNA molecule contained only adenine and thymine bases and the other contained only cytosine and guanine bases. Examine the data in the chart below. DNA with only A/T DNA with only C/G Temp % single strand Temp (C) % single strand 13. Describe the effect that temperature had on each DNA molecule. (C) 37 0 37 0 47 23 47 5 57 52 57 17 14. Propose an explanation for the results in the table above by discussing how changes in structure affect functionality.
