#Unit 3. Fundamental Processes

The first two bases of an mRNA codon always form strong Watson-Crick base pairs with the corresponding bases of the tRNA anticodon and confer most of the coding specificity.

#Unit 3. Fundamental Processes

When inosine (I) is the first (wobble) nucleotide of an anticodon, three different codons can be recognized—the maximum number for any tRNA.

#Unit 3. Fundamental Processes

A minimum of 32 tRNAs are required to translate all 61 codons (31 to encode the amino acids and 1 for initiation).

#Unit 3. Fundamental Processes

Rate of protein synthesis slows down when all three bases of a codon engaged in strong Watson-Crick pairing with the three bases of the anticodon.
