Find the number of nucleotides in an mRNA molecule if it is known that it contains 14 amino acids

Most likely, when writing the problem statement, a mistake was made: instead of the word “contains”, one should write “encodes”, because mRNA does not contain, but encodes amino acids.

With this amendment, the solution: each amino acid is encoded by three nucleotides, which are called a triplet, or codon. Therefore, to obtain a chain of 14 amino acids, 14 triplets or 14 * 3 = 42 nucleotides are required.

Answer: the desired strand of messenger RNA must contain at least 42 nucleotides.
