How many nucleotides are needed to specify three amino acids? (1 point)

Answered by admin @



Take an anticodon, which is simply a three nucleotide base sequence on the tRNA. An anticodon can only carry one amino acid on it, and it has 3 nucleotides. So, take three anticodons, and how many nucleotides do you get? 9! And since an anticodon has 3 nucleotides, and since an anticodon can only have one amino acid riding on it, there must be three anticodons for three amino acids. So, then, a total of 9 nucleotides are needed.

So the answer is 9.
