Answer:
The codon length would not change.
Explanation:
Codons have 3 bases and normally the DNA has 4, each codon counts for a single amino acid. There are 64 possible codon variations which can be calculated by [tex]4^{3}[/tex].
If there were 6 bases in the DNA than there would be [tex]6^{3} = 216[/tex] codon variation that correspond to the same 20 amino acids but the codon lengths would still be the same.
I hope this answer helps.
