You have a piece of DNA that includes the following sequence:
5′-ATAGGCATTCGATCCGGATAGCAT-3′
3′-TATCCGTAAGCTAGGCCTATCGTA-5′
Which of the following RNA molecules could be transcribed from this piece of DNA?

Question

Quizplus · Accepted Answer

RNA is transcribed from the DNA template strand, which is the 3′-5′ strand. To transcribe RNA, we replace thymine (T) with uracil (U), and the resulting sequence is read 5′-3′. Using this information, we can transcribe the DNA sequence as follows: 5′-AUA GGCA UUC GAU CCG GAU AGC AU-3′, which matches option B. Option A has the incorrect nucleotide sequence, and option C has a different order of nucleotides, so neither of them is the correct answer. Thus, the only correct option is B.
