What is called anticodon?
Answers
Answer:
Anticodons are nucleotide sequences that are present on the tRNA that binds to complementary codons present on tRNA.
Explanation:
Each mRNA molecule is made up of four types of nucleotides such as Adenine, Guanine, Uracil, and Cytosine that are termed as A, G, U, and C respectively. All these four nucleotides are arranged in sequence in random in an mRNA and this sequence forms a template/blueprint for protein synthesis.
For example, let's consider the mRNA sequence 'UCACAGGUGAAA'. This mRNA contains codons namely UCA, CAG, GUG, and AAA i.e. the codons are triplet in nature and non-overlapping. Each of the codons is used for adding a particular amino acid residue of a protein. For example, UCA codon adds serine amino acid, CAG codon adds glutamic acid, and so on.
However, we need something to bind and recognize these triplet codons. For the very same reason, tRNA contains anticodons that can bind to the codons in mRNA and recognize them. For example, AGU is an anticodon on serine tRNA that binds to UCA present in the mRNA, GUC is an anticodon present on glutamic acid tRNA that binds to CAG in the mRNA, and so on.
Hence in the process of formation of protein from mRNA (Translation), the anticodon of tRNA helps in forming the correct amino acid sequence of the protein.
