Answer:
5' CAT
Explanation:
The template strand is also known as the coding strand which runs in the 3' to 5' direction as the mRNA is synthesized in the 5' to 3' direction.
In this case the 5' AUG on the mRNA is complementary to the 5'CAU on the methionine tRNA.
This 5' CAU corresponds to the 5' CAT on the template strand of the DNA sequence. This is in reverse to the 5' AUG due to the direction of mRNA synthesis.
