Chapter 3, Problem 23SAE
Summary Introduction
To review:
The meaning of the following terms: codon, triplet, and anticodon.
Introduction:
Gene is the biological unit of heredity. These are present on the chromosomes inside the nucleus in the eukaryotes. The DNA (deoxyribonucleic acid), in turn, is present in the genes. The terms like codon, triplet, and anticodon are associated with the gene.

Which of the following statements correctly explains this fact? The glycine anticodon contains the sequence CC, but the 5' base of the anticodon can pair nonspecifically with the 3' base of the codon. The glycine anticodon contains the sequence CC, but the 3' base of the anticodon can pair nonspecifically with the 5' base of the codon.
