D. AUG
Explicación
## Step 1In the process of transcription, the DNA sequence is copied into mRNA. The DNA sequence is read in the 5' to 3' direction, and the mRNA is synthesized in the 3' to 5' direction.## Step 2The DNA sequence is composed of four types of nucleotides: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). In the DNA sequence, Adenine (A) pairs with Thymine (T), and Cytosine (C) pairs with Guanine (G).## Step 3However, in the mRNA, Thymine (T) is replaced by Uracil (U). Therefore, when the DNA sequence is TAC, the mRNA sequence will be AUG.
