The anticodon of a particular tRNA molecule is:
A
the region that binds to ribosomal RNA
B
the site where amino acids are attached to tRNA
C
a sequence identical to the codon on mRNA
D
a sequence of three nucleotides that is complementary to a specific mRNA codon
Guida verificata passo dopo passo1
Understand that the anticodon is a sequence of three nucleotides found on a tRNA molecule.
Recall that the anticodon pairs with the codon on the mRNA during translation, so it must be complementary, not identical, to the mRNA codon.
Recognize that the anticodon does not bind to ribosomal RNA; instead, it specifically binds to the mRNA codon to ensure the correct amino acid is added.
Know that the site where amino acids attach to tRNA is called the acceptor stem, which is different from the anticodon region.
Conclude that the anticodon is best described as a sequence of three nucleotides complementary to a specific mRNA codon, enabling accurate translation of the genetic code.
