Respuesta :
The anticodon is a combination of nucleotides present on the tRNA, which forms complementary base pairing with the particular codon present on the mRNA.
Further explanation:
The anticodons are present in the tRNA structure. Each tRNA during translation contains a particular anticodon corresponding to the amino acid to be added to the protein sequence being synthesized. This occurs through base pairing between the anticodon in the tRNA and the triplet codon in the mRNA.
During translation or protein synthesis, correct amino acid must be added in the synthesizing chain to produce a functional protein. For this to occur, the tRNA containing the amino acid to be added enters the ribosomal complex. If the base pairing between the anticodon and the codon occurs correctly, the right amino acid is added to the polypeptide chain. Therefore, tRNAs facilitate the addition of correct amino acid to the protein molecule depending on the instructions from the mRNA. The bonding between the codon and the anticodon helps perform this function.
Once the amino acid is linked to the chain, the tRNA leaves the ribosome and another tRNA containing a different or same amino acid, depending on the information from the mRNA, comes in to continue the synthesis of protein. This shows that the anticodon sequence in the tRNA is the RNA version of the original gene.
The anticodons perform the following functions:
- They bring about the formation of a correct amino acid sequence to form a protein.
- The tRNA contains particular amino acid and an anticodon corresponding to its codon. The successful pairing of both codon and anticodon determines that protein synthesis is being done correctly.
- For processing the stored information in the DNA to be turned into a useful protein, the anticodons are required.
