Consider the following two statements about DNA melting temperature:
1) The melting temperature of a sample of DNA is the temperature at which 50% of the double helices in the sample have completely denatured.
2) A molecule with 53% GC base pairs would have a higher melting temperature than a molecule of equivalent length with 53% AT base pairs.
Determine which one of the statements below is CORRECT.
A. Statement 1) and statement 2) are false.
B. Statement 1) and statement 2) are true.
C. Statement 1) is true; statement 2) is false.
D. Statement 1) is false; statement 2) is true.

Given what we know, we can confirm that statement 1 is false, while statement 2 is in fact true. Option D is correct.

Why is statement 1 false and 2 is true?

Statement 1 states that the melting point of DNA is determined by the denaturalization of 50% of the double helices in the sample. This is not the case, since the DNA melting point is when 50% of the sample becomes single-standard DNA. Statement 2 is true in that a higher concentration of GC base pairs leads to a higher melting point for DNA.

Therefore, we can confirm that statement 1 is false, while statement 2 is in fact true. Option D is correct.
