Answer :
Final answer:
An mRNA molecule that is 66 bases long can code for 22 amino acids since each amino acid is encoded by a sequence of three nucleotides. Thus, 66 nucleotides divided by 3 equals 22. Hence the correct option is 22 amino acids.
Explanation:
Understanding mRNA and Amino Acids
The question concerns how many amino acids a 66-base mRNA molecule can code for. Each amino acid in a protein is encoded by a sequence of three nucleotides, known as a codon.
To determine how many amino acids can be produced from 66 nucleotides, you would use the following calculation:
- Divide the total number of nucleotides by the number of nucleotides per amino acid: 66 nucleotides ÷ 3 nucleotides/amino acid = 22 amino acids.
Therefore, an mRNA molecule that is 66 bases long will create a protein composed of 22 amino acids. The other options, such as 66 amino acids or nucleotides, do not align with the codon structure of mRNA.
