Problem

How many different possible 9 bp DNA sequences can code for Arg-Leu-Ser?

a. 18

b. 32

c. 36

d. 144

e. 216

Solution

The translation for a tripeptide would require three different codons, many of which are degenerate, meaning more than one codon can code for the same amino acid. But this degeneracy does not extend to the DNA of the organism as there is strict base pairing during the transcription process. Thus, the number of DNA sequences that can code for this particular tripeptide would be equal to the RNA sequences that would give this translation product.
