Nucleotide triplets that specify amino acids are called:
AThe plasmids
BThe codons
CThe introns
DThe exons
Answer & Solution
Correct answer: B. The codons
1. The units of the genetic code have a specific name.
2. Each amino acid is defined by a three-nucleotide sequence.
3. These nucleotide triplets are called codons.
4. There are 64 codons in total.
