WebEach tRNA anticodon can base pair with one of the mRNA codons and add an amino acid or terminate translation, according to the genetic code. For instance, if the sequence CUA occurred on an mRNA template in the proper reading frame, it would bind a tRNA expressing the complementary sequence, GAU, which would be linked to the amino acid leucine. WebmRNA is held together by hydrogen bonds between complementary nucleotides, while tRNA has strong interactions between the arms of its clover-shaped structure formed by hydrogen bonds and sulfur-containing bases. 2.
