Question

question 18 1 part | -- of 1 point the mrna sequence that is complementary to the sequence atc on dna is aug. uag. auc. tag. atc.

Explanation:

To find the mRNA sequence complementary to the DNA sequence ATC, we use the base - pairing rules for transcription. In DNA - RNA base pairing: Adenine (A) in DNA pairs with Uracil (U) in RNA, Thymine (T) in DNA pairs with Adenine (A) in RNA, and Cytosine (C) in DNA pairs with Guanine (G) in RNA.

For the DNA sequence ATC:

• The first base is A. So in mRNA, it pairs with U.
• The second base is T. So in mRNA, it pairs with A.
• The third base is C. So in mRNA, it pairs with G.

Putting these together, the mRNA sequence is UAG.

Answer:

B. UAG (assuming the options are labeled as A. AUG, B. UAG, C. AUC, D. TAG, E. ATC)
