text: Even before the genetic code had been elucidated, Francis Crick postulated that base pairing of the mRNA codons with the tRNA anticodons would require precision in the first two nucleotide positions but not so in the third position (the precise conformation of base pairs , which refers to the hydrogen bonding between A-T (A-U in RNA) and C-G pairs is known as Watson-Crick base pairing).
