Consider an Escherichia coli bacterium in its natural environment, the human gut. The central dogma allows the controlled expression of genetic information. Replication, transcription, and translation all involve base‐pairing at several levels. For example, mRNA is complementary to one strand of DNA, and the anticodon of tRNA is complementary to the codon in mRNA. In the case of nucleic acids, complementarity generally involves base pairing. ![]() Complementarity is sometimes defined as selective stickiness.
