How many codons are from this mRNA strand? A A A G C G A U A G C U

Group of answer choices

64 codons

Explanation:

The three-letter nature of codons means that the four nucleotides found in mRNA — A, U, G, and C — can produce a total of 64 different combinations. Of these 64 codons, 61 represent amino acids, and the remaining three represent stop signals, which trigger the end of protein synthesis.
