17. When errors in nucleotide sequencing occur,
a. DNA polymerase replaces the incorrect nucleotide with the correct nucleotide
b. enzymes dissolve the incorrect nucleotide so DNA polymerase can add the correct one
c. purines replace pyrimidines in the DNA molecule
d. DNA polymerase proofreads for errors while another enzyme corrects it

[The link from yesterday didn't really help me find my answer...I think it is A]

Thanks
