What tetrapeptide is coded by the following sequence of mRNA? 5'-AUG-GUA-AUG-UUG-3'
A) Met-Val-Met-Leu
B) Ala-Val- Leu-Met

D) Ala-Ala-Met-Leu

Question

The mRNA sequence is translated from 5' to 3', starting with the start codon AUG (which codes for Methionine, Met). Following the sequence, GUA codes for Valine (Val), the second AUG also codes for Methionine (Met), and UUG codes for Leucine (Leu). Therefore, the correct tetrapeptide sequence is Met-Val-Met-Leu.
