Imagine that codons consisted of two bases instead of three, but there were still 20 amino acids. In this scenario, which of the statements below would be true (a), and which would be false (b)?
_____ There would still be enough codons to maintain the fidelity of the genetic code and provide stop codons.
_____ Redundancy would be eliminated; in fact, there would not be enough two-base codons to specify all 20 acids or act as stop codons.
_____ Most codons would probably specify a single amino acid, but if there were still 20 amino acids, then some codons would have to specify more than one amino acid or an amino acid and a stop codon.
Answer:
b There would still be enough codons to maintain the fidelity of the genetic code and provide stop codons.
a Redundancy would be eliminated; in fact, there would not be enough two-base codons to specify all 20 acids or act as stop codons.
a Most codons would probably specify a single amino acid, but if there were still 20 amino acids, then some codons would have to specify more than one amino acid or an amino acid and a stop codon.
