Answer:

The correct answer is B.

Explanation:

Adenine and guanine are purine bases, thymine and cytosine are pyrimidines which make up the structure of the DNA. They are not tautomers. They can however get involved in tautomerism which is the transfer of protons and electrons between chemical compounds that are usually structurally isomers. So the answer is B.

I hope this helps.

Do all mutations result in negative effects? Why or why not?
Sauron [17]

Answer:

No, mutations do not all result in negative effects. Sometimes they can be beneficial, as they are completely random. It is our general tendency to think of the word "mutation" in negative terms; however, do not get confused. Mutations are the root/ultimate source of genetic variation; they are one of the main factors that allow populations to evolve.
