The mRNA produced by the transcription of a gene encoding an oligopeptide is: 5 'AAAUGAAACCAGGAUAAGAAUU3' while the peptide produced by the translation of the above mRNA is: H2N-methionine-lysine-proline-glycine-COOH What is the anticodon of tRNA that will be placed in the ribosome after the cleavage of tRNA, which carries the amino acid lysine? Justify your answer.

Respuesta :

mRNA: 5 'AA AUG AAA CCAGGAUAAGAAUU 3'

Aminoacids: methionine-lysine-proline-glycine

As the first aminoacid is methionine, we know that the first codon must be AUG. Then, the second codon is AAA, which codifies to lysine, so its anticodon of tRNA is given by UUU.
