Question

question 11
mrna: aug gcu gga uaa
what is the correct amino acid sequence?
○ met - ala - pro
○ met - gly - ala
○ met - arg - gly
○ met - ala - gly

Explanation:

Step1: Decode AUG

AUG is the start codon, which codes for Methionine (Met).

Step2: Decode GCU

GCU is a codon that codes for Alanine (Ala).

Step3: Decode GGA

GGA is a codon that codes for Glycine (Gly).

Step4: Decode UAA

UAA is a stop codon, so it does not code for an amino acid. So we only consider the first three codons (AUG, GCU, GGA) as UAA stops translation.

Answer:

Met - Ala - Gly
