In many cases, more than one codon codes for the same amino acid. Because of this, we say that the code is __________.

• A. inaccurate
• B. incomplete
• C. not specific
• D. redundant

Answer: (D)

Verified step by step guidance

1. Understand the concept of genetic code: The genetic code is a set of rules by which information encoded in genetic material (DNA or RNA sequences) is translated into proteins by living cells.
2. Recognize the role of codons: Codons are sequences of three nucleotides that correspond to a specific amino acid or stop signal during protein synthesis.
3. Identify the redundancy in the genetic code: Redundancy means that multiple codons can code for the same amino acid. This is a key feature of the genetic code.
4. Consider the implications of redundancy: Redundancy in the genetic code provides a buffer against mutations, as changes in one nucleotide might still result in the same amino acid being incorporated into a protein.
5. Conclude why the code is described as redundant: The presence of multiple codons for a single amino acid is why the genetic code is considered redundant, ensuring stability and flexibility in protein synthesis.
