Question

Which anticodon would bind to a codon with the sequence 5'-CAG-3'?

Answer 1

The anticodon that would bind to the codon 5'-CAG-3' is 3'-GUC-5' because tRNA anticodons pair with mRNA codons based on complementary base pairing rules.

Step-by-step explanation:

The anticodon that would bind to a codon with the sequence 5'-CAG-3' is 3'-GUC-5'. In RNA transcription, adenine pairs with uracil and cytosine pairs with guanine. Therefore, the anticodon that is complementary to 5'-CAG-3' must have its bases in the reverse order and with the complementary bases.

The anticodon is a consecutive sequence of three nucleotides on a tRNA molecule that is complementary to a specific codon on an mRNA molecule. So, for the mRNA codon CAG, the tRNA would have an anticodon of GUC. The 5' and 3' ends are simply markers of the directionality in the nucleotide sequence of the RNA strands.

Answer 2

The anticodon that would bind to the mRNA codon 5'-CAG-3' is 3'-GUC-5', with base pairing rules ensuring correct anticodon-codon matching for protein synthesis.

Step-by-step explanation:

The anticodon that would bind to a codon with the sequence 5'-CAG-3' would be 3'-GUC-5'. Anticodons are sequences of three nucleotides on a tRNA molecule.

They are complementary to the specific codon on an mRNA molecule. Given that in RNA, adenine (A) pairs with uracil (U) and cytosine (C) pairs with guanine (G), the complement to 5'-CAG-3' would be 3'-GUC-5', because C pairs with G, A pairs with U, and G pairs with C.

This anticodon-codon pairing is critical for the process of translation, where mRNA codons are decoded into a sequence of amino acids during protein synthesis.
