Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Look at your codon chart. The codon CAA will code for the amino acid ____
A
Stop
B
Met
C
glu
D
his
Explanation: 

Detailed explanation-1: -Glutamine is coded by synonymous codons CAA and CAG.

Detailed explanation-2: -According to the A-U C-G rule the corresponding codon to the CAA anticodon is GUU. The genetic code table for translation is related to codons and not to anticodons. The amino acid codified by GUU according to the genetic code is valine.

Detailed explanation-3: -Find a codon’s first base in the first column of the chart; stay in this row. Find the second base in the middle of the chart, stay in this box. Locate the third base in the far right column, this is the amino acid that matches the mRNA codon.
