How many triplet codes does DNA sequence contain?

DNA sequences contain triplet codes, known as codons, which are composed of three nucleotide bases. Since there are four different nucleotide bases (adenine, thymine, cytosine, and guanine), the total number of possible unique codons is 64 (4^3). These codons correspond to 20 amino acids and serve as the building blocks for protein synthesis. Each triplet code specifies a particular amino acid or a stop signal during translation.
