Answer:

The answer is B

Explanation:

The small piece of a DNA molecule contains no base pairing errors:

T goes with A __ C goes with G __ G goes with C

B. TCTCG

   AGAGC

TCT CG

AGA GC

contains no base-pairing errors.

What is base pairing?

  • Adenine (A), thymine (T), guanine (G), and cytosine (C), according to the Watson-Crick base pairing, which is the basis for the helical structure of double-stranded DNA.
  • Inside the DNA molecule, A only interacts with T, and C only interacts with G.
  • Thymine is swapped out for uracil (U) in RNA.

Thus, we can conclude that option B is correct.
