A) \[5\text{ }UUU\text{ }ACG\text{ }CGC\text{ }UAU\text{ }3\]and \[3AAA-UGC-GCG-AUA\text{ }5\]
B) \[5UAU\text{ }CGC\text{ }GCA\text{ }UUU3\]and \[3AUA-GCG-CGU-AAA\text{ }5\]
C) \[5UUU\text{ }ACC\text{ }TUG\text{ }UAU\text{ }3\]and \[3AAA-UGG-UAC-AUA\text{ }5\]
D) \[5UAU\text{ }GUT\text{ }CCA\text{ }UUU\text{ }3\]and \[3AUA-CAU-GGU-AAA\text{ }5\]
Correct Answer: A
Solution :
: For the given sequence of nucleotides on a gene, mRNA formed against it and the sequence of bases in the corresponding binding anticodons will be as follows. Given sequence of nucleotides: \[yAAA\text{ }TGC\text{ }GCG\text{ }ATA\text{ }5\] (This strand has polarity 3 \[\to \] 5, which acts as a template DNA) After transcription the sequence of mRNA will be: \[5UUU\text{ }ACG\text{ }CGC\text{ }UAU\text{ }3\] (Polarity is 5 \[\to \] 3, because DNA-dependent RNA polymerase catalyzes the polymerization I n only one direction, i.e., 5 \[\to \] 3) Anticodons: \[37AAA-UGC-GCG-AUA\text{ }5\] (It has bases complementary to the code on mRNA).
