2 mrna a c a c u u
3 trna g a a
4 protein

Explanation:

Step1: Recall base - pairing rules for transcription

In transcription from DNA to mRNA, A (adenine) pairs with U (uracil), T (thymine) pairs with A, G (guanine) pairs with C (cytosine), and C pairs with G. Given the DNA sequence TGTGAA, the mRNA sequence is ACACUU.

Step2: Recall base - pairing rules for tRNA - mRNA interaction

In the interaction between tRNA and mRNA, the base - pairing is complementary. So for the mRNA sequence ACACUU, the tRNA anticodon sequence is UGUGAA.

Step3: Determine amino - acids from mRNA codons

Using the genetic code, the mRNA codons ACA codes for Threonine and CUU codes for Leucine.

Answer:

The tRNA sequence is UGUGAA. The amino - acids in the protein are Threonine and Leucine.
