Answer:
The correct answer is "Identical copies of the original DNA would not be formed".
Explanation:
Hydrogen bonding between nitrogenous bases in DNA is one of the characteristics that makes unique the sequences of DNA. This is known as complementary base pairing, at which in regular conditions cytosine could only bind with guanine by forming three hydrogen bonds, and adenine with thymine by forming two hydrogen bonds. If hydrogen bonds could be formed between any two nitrogenous bases in DNA, the formation of identical copies of the original DNA would not be possible. DNA polymerase identifies the next nucleotide during polymerization by complementary base pairing, if this mechanism did not exist DNA polymerase would not be able to make identical copies of DNA.
