What technique could tell you how gene expression differs between individuals with and without cystic fibrosis?

RNA-seq (RNA sequencing) is a technique that could be used to tell how gene expression differs between individuals with and without cystic fibrosis. RNA-seq is a high-throughput method that allows for the quantification of gene expression levels by sequencing millions of RNA molecules in a sample. By comparing the RNA-seq data from individuals with and without cystic fibrosis, researchers can identify genes that are differentially expressed between the two groups, providing insights into the molecular basis of the disease.
