The Replication Fork: Lagging Strand Choreography

Primase Adds RNA primer for Pol III to start. The DNA double helix is ready to be replicated. The Replication Fork: Lagging Strand Choreography lets you explore this hands-on instead of only reading about it.

Explores the molecular mechanisms of DNA replication, the flow of genetic information from gene to protein, and the regulation of gene expression in prokaryotes and eukaryotes. It focuses on DNA and RNA Structure, DNA Replication, Transcription and RNA Processing, Translation, Regulation of Gene Expression (Operons), Gene Expression and Cell Specialization from the “Unit 6: Gene Expression and Regulation” section.

AP Biology is an introductory college-level course that explores the complexity of living organisms through inquiry-based investigations and hands-on laboratory work. The curriculum is organized around four Big Ideas: E… This demo is the interactive piece for the “Unit 6: Gene Expression and Regulation” section.

You'll build intuition for DNA and RNA Structure, DNA Replication, Transcription and RNA Processing, Translation, Regulation of Gene Expression (Operons), Gene Expression and Cell Specialization — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on AP Biology alone.
