Question

If the dna sequence is TAC CCC AAG CTC GGT ATC. what is mRNA tRNA AA?

Answer 1

The mRNA sequence would be:

AUG GGG UUC GAG CCA UAG

The mRNA sequence is complementary to the DNA sequence, in other words would just basically mean you do the opposite of the bases to the DNA sequence such that:

Cytosine with Guanine

Thymine (uracil for RNA) with Adenine

However, mRNA has Uracil instead of Thymine, so instead the uracil in mRNA binds with adenine.

Urcacil with Adenine

For tRNA, they have anticodons, meaning they have bases complementary to the mRNA strand, so the tRNA with the complementary anticodon sequence would be:

UAC CCC AAG CUC GGU AUC (DNA sequence but replace thymine with uracil)

For the amino acids, they would bond to the specific tRNA molecules with the specific bases on the anticodons.
