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?
UAA
To determine the sequence of bases on the opposite strand assembled by the tRNA, you need to understand the pairing rules between mRNA codons and tRNA anticodons. The pairing rules state that adenine (A) on the mRNA codon pairs with uracil (U) on the tRNA anticodon, cytosine (C) on the mRNA codon pairs with guanine (G) on the tRNA anticodon, guanine (G) on the mRNA codon pairs with cytosine (C) on the tRNA anticodon, and uracil (U) on the mRNA codon pairs with adenine (A) on the tRNA anticodon.
In this case, the mRNA codon is AUU. Based on the pairing rules, the anticodon on the tRNA would be UAA. Therefore, the sequence of bases on the opposite strand assembled by the tRNA is UAA.
To determine the sequence of bases on the opposite strand assembled by the tRNA, we need to remember the base pairing rules in DNA/RNA:
- Adenine (A) pairs with Thymine (T) in DNA or Uracil (U) in RNA.
- Thymine (T) pairs with Adenine (A) in DNA.
- Guanine (G) pairs with Cytosine (C).
Given that the mRNA codon sequence is AUU, we can determine the corresponding sequence on the opposite strand assembled by the tRNA.
mRNA: A U U
tRNA: U A A
Therefore, the sequence of bases on the opposite strand assembled by the tRNA would be UAA.
