The "melting point" of a DNA molecule is the temperature at which the double-helical strand breaks apart. Suppose you are given two DNA samples. One sample, sample A, contains 45% G-C base pairs, while the other sample, sample B, contains 64% G-C base pairs. The total number of bases is the same in each sample. Which of the two samples, sample A or sample B, has a higher melting point?
A. sample A
B. sample B
C. The melting point is the same for both.

A protein structure is solely determined by the sequence of amino acids in the
primary structure. Suppose that you were to genetically engineer a new protein by
keeping the exact same sequence, but it was completely reversed in the order of
amino acids compared to the original. Would the new protein have the same tertiary
structure as the original? Why?
