Question

Which one of the following experimental designs is most suited to answer whether a newly discovered transposable element in yeast, transposes through an mRNA intermediate?

Options

Choose one · Correct answer highlighted

Sequence the transcriptome of the yeast cell to see the presence of a corresponding mRNA. Introduce an intron which can be spliced out, in the transposable element and test the presence or absence of the intron at a newly transposed site. Correct Block transcription and then test whether transposition occurs. Using a suitable bioinformatics tool predict whether an mRNA intermediate can be formed

Explanation

In molecular biology, nucleic acid structure and recombination dictates that hairpin formation, Holliday junction resolution and translation control ensure fidelity. Therefore Introduce an intron which can be spliced out, in the transposable element and... is correct as it matches molecular mechanisms, supported by mechanistic studies and conserved across related systems.
