Quizplus · Accepted Answer

The Northern blot hybridization technique is widely used to detect gene expression at the transcriptional level, where the RNA molecules are separated by size, transferred to a membrane, and hybridized with a specific DNA probe. This technique allows for the detection of specific mRNA transcripts and an estimation of their abundance, which can be used to study gene regulation, developmental processes, and diseases.
