Verified step by step guidance

Understand the central dogma of molecular biology, which describes the flow of genetic information from DNA to RNA to protein.

Recognize that the DNA coding sequence is transcribed into mRNA. In this case, the DNA triplet 'AAA' is transcribed into the mRNA codon 'UUU'.

Recall that tRNA molecules have anticodons that are complementary to mRNA codons. The anticodon is responsible for recognizing and binding to the mRNA codon during protein synthesis.

Determine the complementary base pairing rules: Adenine (A) pairs with Uracil (U) in RNA, and Thymine (T) pairs with Adenine (A) in DNA. In RNA, Uracil (U) replaces Thymine (T).

Apply the complementary base pairing rules to find the anticodon on the tRNA. Since the mRNA codon is 'UUU', the anticodon on the tRNA will be 'AAA'.
