If there were six bases in DNA and still only 20 amino acids, how long would a codon need to be in order to specify an amino acid?

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 .

If there were 6 bases in the DNA than there would be codon variation that correspond to the same 20 amino acids but the codon lengths would still be the same.

I hope this answer helps.

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides

1. is geographic distribution

2 is increasing complexity

3 is transitional forms
