Question

During translation, nucleotide base triplets (codons) in mRNA are read in sequence in the 5’ → 3’ direction along the mRNA. Amino acids are specified by the string of codons. What amino acid sequence does the following mRNA nucleotide sequence specify?

5'-AUGGCAAGAAAA-3'
Express the sequence of amino acid using the three-letter abbrevations, separated by hyphens.(e.g.,Met-Ser-Thr-Lys-Gly).

Answer 1

Answer: N-ter-Met-Ala-Arg-Lys-C-ter

Explanation: The genetic code expresses what aminoacid codifies a codon or triplet in the RNA sequence. The RNA sequence 5'-AUGGCAAGAAAA-3 codify a peptide compund by 4 aminoacids, from the 5' or N-ter in the peptide to the 3' or C-ter in the peptide: Methionine (Met), Alanine (Ala), Arginine (Arg) and Lysine (Lys).
