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 solve the question of how many amino acids can be produced from an mRNA consisting of 282 nucleotides, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Basics of mRNA and Amino Acids**:
- mRNA (messenger RNA) is transcribed from DNA and carries the genetic information to the ribosome, where proteins are synthesized.
- Each amino acid in a protein is encoded by a sequence of three nucleotides in mRNA, known as a codon.

2. **Calculate the Number of Codons**:
- Since each codon consists of three nucleotides, we can determine the number of codons in the mRNA by dividing the total number of nucleotides by 3.
- Formula: Number of codons = Total nucleotides / 3

3. **Perform the Calculation**:
- Given that the mRNA consists of 282 nucleotides:
\[ \text{Number of codons} = \frac{282}{3} = 94 \]

4. **Conclusion**:
- Since each codon corresponds to one amino acid, the mRNA can produce a polypeptide chain consisting of 94 amino acids.

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