To recognize the amino acid carried by tRNAs with the following anticodon sequences. a. 5 ' -UAG-3 ' b. 5 ' -AAA-3 ' c. 5 ' CUC-3 ' d. 5'-AUG-3' e. 5'-GAG-3' Introduction: The sequence of the three nucleotides forming a unit of genetic code (Amino acid) corresponding to a complementary codon in m-RNA is anticodon. There are 61 different codons for the amino acids and also three stop codons and one start codon (AUG) which code for the methionine. Each t-RNA (Transfer RNA) has an anticodon which is complementary to the m-RNA while the end of the t-RNA carries the amino acid for which the anticodon codes. Each codon codes for a specific amino acid, for example, AUG codes for methionine. There are 20 amino acids. Sometimes, more than one type of codons code for single amino acid, for example, the amino acid serine is coded by four types of codons UCU, UCC, UCA, and UCG.
