The DNA code is a triplet code. Each triplet which consists of a group of three bases describes the codes for a specific amino acid:
1. The triplet of bases on the DNA and mRNA is known as a codon.
2. The triplet of bases on the tRNA is known as an anti-codon.
3. Each mRNA codon codes for a specific amino acid.
The anti-codons and codons match up and form complementary base pairs.
The recognition/landing dock on the tRNA is called an anticodon since it will match up with the codon.
