Question

Which of the following DNA coding sequences would produce this mRNA?mRNA: UUCAAUGCCUCAAGGUUAAAGCGGCGGAAGTTACGGAGTTCCAATTTCGCCGCCTTCAATGCCTCAAGGTTAAAGCGGCGGUUCAAUGCCUCAAGGUUCCCGCGGCGGAAGUUACGGAGUUCCAAUUUCGCCGCC

Answer 1

WhAaaaAAAaaaaAAAAAAAAaaaaaaaaa

Answer 2

mRNA is obtained from DNA, and has a complementary sequence taking into account that adenine binds to thymine and guanine to cytosine, but also replacing thymine with uracil in RNA. Therefore, the complementary sequence of the mRNA (the DNA) would be as follows:

mRNA: UUCAAUGCCUCAAGGUUAAAGCGGCGG

DNA: AAGTTACGGAG TTC CAATTTCGCCGCC

Therefore, the answer is the first option.
