Question
What kinds of information can we obtain from a Northern blot?
Step 1
A Northern blot is a laboratory technique used to detect specific RNA molecules within a sample. It involves the separation of RNA by gel electrophoresis, transfer to a membrane, and hybridization with a labeled probe. Show more…

Northern blotting, RT-PCR, and microarrays can be used to analyze gene expression. A lab studies yeast cells, comparing their growth in two different sugars, glucose and galactose. One student is comparing expression of the gene $H M G 2$ under these two conditions. Which technique(s) could he use and why? Another student wants to compare expression of all the genes on chromosome $4,$ of which there are approximately $800 .$ What technique(s) could she use and why?
