The Message, Not the Protein

You'll learnhow RNA polymerase reads one template strand to build a single strand of RNA.

RNA polymerase reads one strand of a gene and builds a strand of RNA — not a protein, not ever — and in a eukaryote that strand is edited before it is allowed to leave the nucleus. Ten short steps; press Next for each one.

DNA → RNA · template 3′→5′ · RNA 5′→3′ · then cap, tail, splice

Before you start

What you're looking at

One gene, drawn flat: a grey coding strand above the pale violet template strand RNA polymerase will read.

The question

Which strand gets read, what does transcription produce, and why is that product edited?
