Northern Blotting: Basic Principles

Northern blotting is a molecular biology technique used to study gene expression by detecting specific RNA sequences within a sample. This method allows researchers to measure the size and quantity of RNA molecules, providing insights into the gene's transcriptional activity.

Steps in Northern Blotting:

1. RNA Extraction: The first step involves isolating total RNA from the cells or tissues of interest. This extraction must be done carefully to avoid degradation of RNA by RNases.

2. RNA Separation: The extracted RNA is then separated by size using agarose gel electrophoresis. This step is crucial _______ ________ ________ _________ _________ _____ _______.
