anticodon

Detailed explanation-1: -An anticodon is a unit of three nucleotides corresponding to the three bases of an mRNA codon. Each tRNA has a distinct anticodon triplet sequence that can form 3 complementary base pairs to one or more codons for an amino acid. Some anticodons pair with more than one codon due to wobble base pairing.
Detailed explanation-2: -anticodon – a sequence of three nucleotides on a tRNA molecule that bond to a complementary sequence on an mRNA molecule. The anticodon sequence determines the amino acid that the tRNA carries.
Detailed explanation-3: -With RNA, the nucleotide base adenine always pairs with uracil (A and U), and guanine always pairs with cytosine (G and C). Some other codon and anticodon examples are: Methionine: the mRNA codon is AUG, and the tRNA anticodon is UAC. Lysine: the mRNA codon is AAG and the tRNA anticodon is UUC.
Detailed explanation-4: -The 3’ end has CCA sequence. Attachment of an amino acid to the 3’ adenosine yields an aminoacyl-tRNA and therefore the CCA site is called amino acid binding site; option D is correct.
