Detailed explanation-1: -An anticodon is a trinucleotide sequence located at one end of a transfer RNA (tRNA) molecule, which is complementary to a corresponding codon in a messenger RNA (mRNA) sequence.
Detailed explanation-2: -The anticodon of any one tRNA fits perfectly into the mRNA codon that codes for the amino acid attached to that tRNA; for example, the mRNA codon UUU, which codes for the amino acid phenylalanine, will be bound by the anticodon AAA.
Detailed explanation-3: -Examples of codon include alanine, valine, leucine and serine. Examples of anticodon include the codon CGA codes for the cysteine amino acid and amino acid.
Detailed explanation-4: -Alanine is encoded by the four codons of the GC box (GCA, GCG, GCU, and GCC). Known alanine anticodons include the UGC, IGC, and VGC triplets (I = inosine; V = uridine-5-oxyacetic acid).
