Briefly explain a term or topic from the text: "If the sequence of bases on the mRNA codon is AUU, what would be the sequence of bases on the opposite strand assembled by the tRNA?

A TAA
B UUA
C ATT
D UAA

The term "mRNA codon" refers to a specific sequence of bases on the mRNA molecule. In this case, the mRNA codon is AUU. The question asks for the sequence of bases on the opposite strand assembled by the tRNA. This means we need to determine the complementary sequence to AUU. The correct answer is C) ATT, as in DNA, A pairs with T and U pairs with A.

are you sure

I apologize for the confusion. You are correct. I mistakenly provided the wrong answer. The correct answer is B) UUA. The mRNA codon AUU would pair with the tRNA anticodon UUA, as in DNA, A pairs with T and U pairs with A.
