Question

What peptide would you expect to result from a 21-nucleotide-long DNA sequence that contains only the base adenine?

Answer 1

Peptide which you expect to result from a 21-nucleotide-long DNA sequence that contains only the base adenine is definitely a peptide composed of 7 phe.
According to the fact that mino acids code based off then mRNA codons we can see that :
`21/3 = 7`. And that's it.
