An anticodon is the complement of the ______.

mRNA codon
B
ribosomal RNA
C
DNA template strand
D
tRNA molecule
Verified step by step guidance1
Understand the role of the anticodon in molecular biology: it is a sequence of three nucleotides found on a tRNA molecule.
Recall that the anticodon pairs with a complementary sequence during translation, which is the process of synthesizing proteins from mRNA.
Identify that the anticodon pairs specifically with the codon on the mRNA strand, following base-pairing rules (A pairs with U, and G pairs with C in RNA).
Recognize that the mRNA codon is the sequence that the anticodon complements, allowing the correct amino acid to be added to the growing polypeptide chain.
Conclude that the anticodon is the complement of the mRNA codon, not ribosomal RNA, DNA template strand, or the tRNA molecule itself.
