If the nucleotides 5'-GAT-3' are paired with the nucleotides 3'-CUA-5', the pairing must be __________.
arlik [135]

Answer:

The correct answer is A.) during transcription

Explanation:

The pairing during DNA replication and transcription is a little bit different. During replication, A pairs with T, T with A, C with G, and G with C. In transcription T is replaced by U so when there is nucleotide adenine is present in the DNA sequence than uracil will be added against it as complementary nucleotide in mRNA during transcription.

So here 5'-GAT-3' nucleotide sequence is present in DNA and after transcription the nucleotide sequence will be 5'-CUA-5' because U is added against A during transcription. Therefore the correct answer is A.

Honey can be extracted only two or three times a year from a traditional beehive. A modern beehive produces double to triple the volume of honey compared to a traditional hive.
