Question

The U2 snRNA basepairs with

Options

Choose one · Correct answer highlighted

a sequence spanning the exon intron splicing site the 3’ splice site of the intron a sequence spanning the intron exon splicing site the branched sequence in the intron Correct

Explanation

nucleic acid structure and recombination analysis shows hairpin formation, Holliday junction resolution and translation control ensure fidelity. Consequently the branched sequence in the intron emerges as the valid choice since it matches molecular mechanisms, aligning with established principles in molecular biology literature.
