Answer:B

When it comes to RNA A will always pair U. When there is T present always pair it to A.

In the given question, the complementary segment of mRNA is CUA and GGC.

What is complementarity?

It illustrates an association between two compositions each following the principle of lock and key. Complementarity in nature is the base principle of DNA transcription and replication as it is a characteristic shared between two RNA or DNA sequences.

It is attained by different associations between the nucleobases, that is,

  • Adenine
  • Thymine (uracil in RNA)
  • Guanine
  • Cytosine

The thymine, uracil and cytosine are pyrimidines, while the adenine and guanine are purines. Both kinds of molecules complement each other and can only pair with the opposing kind of nucleobase. That is adenine base pairs with thymine (uracil in RNA), and cytosine base pairs with guanine.

Therefore, the short DNA segment, that is, GATCCG would complement with the CUAGGC segment of mRNA, as Adenine pairs with uracil and cytosine pairs with guanine.

Thus, the correct answer is option B.
