RNA sequencing

(… SEE-kwen-sing)
A laboratory method used to learn the exact sequence (order) of the building blocks that make up all RNA molecules in a cell. In a cell, RNA is copied from pieces of DNA and contains information to make proteins and perform other important functions. RNA sequencing is used to learn more about which genes are expressed (turned on) in different types of cells and when and how these genes are expressed. This may help researchers understand the cause of certain diseases, such as cancer.
