The mRNA Consisting of 282 nucleotides can produce a polypeptide chain of

Options

A. 282 amino acids
B. 120 amino acids
C. 93 amino acids
D. 94 amino acids

Answer

To determine how many amino acids a polypeptide chain can produce from an mRNA consisting of 282 nucleotides, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Genetic Code**: The genetic code is read in triplets, meaning that three nucleotides correspond to one amino acid. This is a crucial point because it establishes how we will convert the number of nucleotides into the number of amino acids.

2. **Calculate the Number of Amino Acids**: To find out how many amino acids can be produced from the mRNA, we need to divide the total number of nucleotides by the number of nucleotides that code for one amino acid.
\[ \text{Number of amino acids} = \frac{\text{Total nucleotides}}{3} \]

3. **Perform the Calculation**:
\[ \text{Number of amino acids} = \frac{282}{3} = 94 \]

4. **Conclusion**: Therefore, an mRNA consisting of 282 nucleotides can produce a polypeptide chain of 94 amino acids.

### Final Answer:
The mRNA consisting of 282 nucleotides can produce a polypeptide chain of **94 amino acids**.
