Question

the genetic code is often described as redundant. what feature of the genetic code does this reference? view available hint(s)for part a one trna can match with multiple codons, bringing the same amino acid each time. most amino acids have more than one codon. any single letter in the triplet codon can be ignored and still result in the same amino acid. a single codon can be used for many different amino acids.

Answer 1

The redundancy of the genetic code references the fact that most amino acids, including threonine, are encoded by multiple codons, diminishing the potency of mutations on protein functions.

Step-by-step explanation:

When describing the genetic code as redundant, we're referring to the fact that most amino acids are encoded by more than one codon. Regarding threonine, four codons (ACU, ACC, ACA, and ACG) specify this amino acid. This redundancy, also known as degeneracy, offers an advantage as it lessens the impact of mutations on protein synthesis. A base change in one position of the codon often results in the incorporation of the same or a similar amino acid, preventing the protein from becoming nonfunctional. Codons with different third positions are an example of the 'wobble' concept, underscoring the flexibility of the third base in codon-anticodon pairing which contributes to the redundant nature of the genetic code.
