Final answer:
The anti-codon in tRNA that corresponds to the DNA sequence TTT during protein synthesis is AAA.
Step-by-step explanation:
If DNA reads TTT, then the anti-codon in the tRNA during protein synthesis will read AAA. This is because during transcription, DNA is used as a template to synthesize mRNA, which means that adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). However, in RNA, uracil (U) replaces thymine. So the mRNA sequence complement to TTT in the DNA is AAA. During translation, tRNA molecules recognize specific mRNA codons through their anti-codons. Thus, the tRNA anti-codon that complements the mRNA codon AAA is UUU. However, it is important to remember that the initial question asks for the tRNA anti-codon corresponding to the DNA sequence TTT, and not the mRNA codon, which is why the correct answer is AAA.
