If a DNA triplet is ATG, the corresponding mRNA triplet will be ____, and the corresponding tRNA triplet will be ____.
A)TAC/TAC
B)UUC/AAG
C)UAG/ATC
D)UAC/AUG

- The corresponding mRNA triplet to the DNA triplet ATG is AUG because in transcription, DNA (which uses the bases A, T, G, and C) is converted to mRNA (which uses the bases A, U, G, and C) and A pairs with U and T pairs with A. 
- The corresponding tRNA triplet to the mRNA triplet AUG is UAC because in translation, mRNA is converted to tRNA according to the genetic code and the pairing of codons (three-base sequences) and anticodons (the complementary sequences on tRNA). The anticodon on the tRNA that pairs with the codon AUG (which codes for the amino acid methionine) is UAC.
