What you’ll learn

  1. From DNA to RNALocate promoters, distinguish template and coding strands, and recognize RNA processing in eukaryotes.Build complementary RNA from the template, respect U-for-T pairing, and ask whether the diagram shows primary or mature transcript.

Questions this course answers

Where does transcription begin?

The promoter helps position transcription machinery.

What happens to introns in many eukaryotic transcripts?

Splicing removes introns and joins exons in mature mRNA.

Which strand is read to build RNA?

Polymerase reads the template to synthesize complementary RNA.
