Review Questions
... DNA, the recipe for making proteins, never leaves the nucleus (nucleoid region in bacteria). Yet all the protein-making machinery is located out in the cytoplasm. So how does the information get to the cytoplasm? DNA is transcribed into messenger RNA. 2. What is a transcript? A transcript is not a c ...

RNA-Seq
RNA-seq (RNA sequencing), also called whole transcriptome shotgun sequencing (WTSS), is a technology that uses the capabilities of next-generation sequencing to reveal a snapshot of RNA presence and quantity from a genome at a given moment in time.
