Final answer:
tRNA has anticodons that bind to codons on mRNA during protein synthesis. Each tRNA carries a specific amino acid and recognizes a specific codon. Some tRNAs can recognize multiple codons.
Step-by-step explanation:
tRNA has anticodons that bind to the codons on mRNA during protein synthesis. Each tRNA carries a specific amino acid and recognizes a specific codon. For example, a tRNA with an anticodon GGC will bind to a codon CCG. Some tRNAs can recognize multiple codons due to wobbling. There are around 60 to 90 species of tRNA in bacteria, with each tRNA carrying the same amino acid as others with the same anticodon.
