In the context of the triplet code in organic chemistry, which can produce 64 possible codon combinations, what is an advantage of this redundancy?
A
It ensures that each amino acid is coded by only one unique codon, increasing specificity.
B
It limits the number of amino acids that can be synthesized, simplifying protein synthesis.
C
It increases the likelihood of translation errors during protein synthesis.
D
It allows for multiple codons to code for the same amino acid, reducing the impact of mutations.
Verified step by step guidance1
Understand the concept of the triplet code: In organic chemistry, particularly in the context of genetics, the triplet code refers to the three-nucleotide sequences in DNA or RNA that correspond to specific amino acids or stop signals during protein synthesis.
Recognize the redundancy in the genetic code: There are 64 possible codon combinations (4 nucleotides taken three at a time: 4^3 = 64), but only 20 standard amino acids. This means that multiple codons can code for the same amino acid, a phenomenon known as redundancy or degeneracy of the genetic code.
Consider the implications of redundancy: Redundancy in the genetic code means that if a mutation occurs in one nucleotide of a codon, it might still code for the same amino acid, thus reducing the potential negative impact of mutations on protein synthesis.
Evaluate the options given: The statement 'It allows for multiple codons to code for the same amino acid, reducing the impact of mutations' correctly describes the advantage of redundancy in the genetic code.
Conclude the analysis: The redundancy in the genetic code is beneficial because it provides a buffer against mutations, ensuring that proteins are synthesized correctly even if minor errors occur in the DNA sequence.
