If a mutation changes a G to an A on one strand of a DNA molecule,with a corresponding change in its complement,which property will most likely be affected?
A) The width of the DNA molecule
B) The length of the DNA molecule
C) The nature of protein-DNA interactions
D) The number of purines in the double-stranded molecule
E) All of the above are equally likely.

The change of a single nucleotide base pair may alter the amino acid sequence of a protein if it occurs in a codon that specifies an amino acid. This can affect the nature of protein-DNA interactions, as a change in the amino acid sequence can potentially affect the binding ability of the protein to specific DNA sequences. The other choices (A, B, and D) are not directly related to the specific nucleotide base pair change described in the question.
