Question
Indicate whether each of the following statements about the relationship between codons and amino acids is true or false. 1. The start codon has a dual function because it also codes for an amino acid. 2. Most codons code for more than one amino acid 3. Most amino acids are specified by more than one codon. 4. Only 20 different codons are used to code for amino acids. 5. In some cases, it is possible to change the sequence of bases in a codon and it will still code for the same amino acid 6. All codons code for amino acids.Explanation / Answer
True. The start codon AUG codes for the amino acid methionine/N-formyl methionine.
False. A codon codes for only one amino acid.
True. Since there are 20 amino acids and 64 possible codons, there is degeneracy of the genetic code. An amino acid can be coded by more than one codon.
False. There are 64 codons, out of which three are stop codons. The remaining 61 codons code for amino acids.
True. Due to Wobble pairing, the change in last nucleotide of a codon can still code for the same amino acid.
False. Three of the codons are stop codons and do not code for any amino acid.
