AThree bases
BTwo bases
CFour bases
DSix bases
Answer & Solution
Correct answer: A. Three bases
1. The genetic code reads DNA in fixed-size chunks.
2. Each amino acid is defined by a three-nucleotide sequence.
3. That sequence is called the triplet codon.
4. Three messenger RNA nucleotides correspond to one amino acid in the polypeptide.
