What hybridization technique can be used to confirm if two genes are components of an operon by estimating transcript size?

Question

Northern blotting involves separating RNA molecules based on their size and using a labeled probe to detect the presence of specific RNA transcripts. By performing a northern blot with probes for the two genes in question, we can determine if they are both transcribed within the same transcript or if they are transcribed separately. This can confirm if they are components of an operon or not. Southern blotting is used to detect specific DNA sequences, not RNA. Formaldehyde cross-linking is a technique used to study protein-DNA interactions. Agarose gel electrophoresis is a general technique for separating biomolecules based on size or charge. Isoelectric focusing is a technique for separating proteins based on their isoelectric point.
