Question

a strand of mrna has the bases guanine - cytosine - uracil. which amino acid corresponds to these bases?
messenger
rna codons
a. cys
b. arg
c. ala
d. ser

Explanation:

Step1: Identify the codon

The codon is GCU (guanine - cytosine - uracil).

Step2: Locate in the codon table

First base \( G \), second base \( C \), third base \( U \).
Looking at the codon table:
For the first base \( G \) (row), second base \( C \) (column), and third base \( U \).
The corresponding amino acid is Ala (Alanine).

Answer:

C. Ala
