Question

Of the following codons, which encodes a normal translational stop?

A) UUU
B) AUG
C) UAG
D) AAA
E) AGG

Answer 1

The codon that encodes a normal translational stop is UAG. Therefore, the correct option is C.

Step-by-step explanation:

The codon that encodes a normal translational stop is UAG.

Stop codons are sequences of three nucleotides in mRNA that signal the termination of translation, releasing the polypeptide from the ribosome. In addition to UAG, the other two stop codons are UAA and UGA.

These stop codons do not code for any amino acids and are also known as termination or nonsense codons.
