Early hypothesis was not based on experimentation
Given what we know, we can confirm that the sequence on tRNA that is opposite to the codon on mRNA is the anticodon.
<h3>What is an anticodon?</h3>
This is the codon on the tRNA strand that is opposite to the mRNA codon. This opposite nature allows them to attract one another and enable their pairing in order to deposit the corresponding amino acid for protein synthesis.
Therefore, we can confirm that the sequence on tRNA that is opposite to the codon on mRNA is the anticodon.
