The correct answer is option B – AUUCGUAAGGCUC. The corresponding sequence to the DNA sequence (TAAGCATTCCGAG) as a result of transcription is AUUCGUAAGGCUC. This question is testing your knowledge of base pairing, specifically in transcription. Transcription is the process whereby the DNA sequence of a gene is copied to produce mRNA, which is needed for protein synthesis.
DNA sequence uses the complementary base pairing of guanine and cytosine, thymine, and adenosine, while on the mRNA produced, you have nucleotides such as adenine, Uracil, cytosine, and guanine. Thymine is replaced by Uracil. Since the DNA sequence is complementary to mRNA produced, a on the DNA on the DNA sequence will be matched by U on mRNA, and G on DNA sequence is matched by C on mRNA.
