How many nucleotides are needed to specify three amino acids?

A codon of three bases codes for a single amino acid, therefore three codons should code for three amino acids.

to code for one aminoacid one codon,ie, three nucleotidal sequences are required.but to specify a polypeptide consisting of three aminoacids,5 codons are required.1 initiating codon-AUG,three coding...

i think nine bases are needed for three amino acids because i think it takes three bases to make one amino acid

The answer is nine because one codon has 3 letters. The above answer is completely incorrect. The question is how many codons are necessary to specify three amino acids, not bases (letters). As my...

3 are needed. As there are 20 amino acids used in proteins, each amino acid would have to be encoded by a minimum of three nucleotides. For example, a code of two consecutive nucleotides could...
