Find a video lesson on this sub-topic at Dan Rott videos.

Click on ‘The Central Dogma of Biochemistry’ to see an Interactive Animation from Wiley or click on ‘Protein Synthesis’ to see a different Interactive Animation from Wiley.

Fantastic animated tutorials from McGraw Hill Education – stages of Transcription, Exons & Introns & Transcription compared to DNA Replication.

Regulated Transcription in under 4 minutes from ndsuvirtualcell

Gene Regulation – a 10m video from Mr Andersen. He also explains Transcription & Translation in a 12m tutorial.


2.7 DNA Replication, Transcription & Translation

BioKnowledgy 2.7 DNA replication, transcription and translation from Chris Paine (at Dulwich College Shangai) – taken from his fabulous blog BioKnowledgy.

DNA Replication, Transcription, & Translation in 10m from roxprice:

Many assessment statements are also covered by Stephanie Castle (with more being added all the time).


A short, simple animation to show DNA replication & here’s an animated tutorial from McGraw Hill Education – structural basis of DNA Replication

In Crash Course Biology #10 – DNA Structure & Replication, Hank introduces us to that wondrous molecule DNA and explains how it replicates itself in our cells.


For the Polymerase Chain Reaction – click on ‘PCR’ to see an Interactive Animation from Wiley or here for two animated tutorials from McGraw Hill Education – PCR reactions & PCR. Or why not use PCR yourself in a Virtual Lab from Learn.Genetics (labs on PCR & DNA extraction). Or there’s a 12m PCR for A level video; a 4m video on PCR hereand from the DNA Learning Center (1m 28s):

The PCR song:

MESELSON & STAHL experiment (proof of semi-conservative replication)

Great animation from McGraw-Hill and here’s a video of The most beautiful experiment in Biology (7m 33s).


Transcription & translation, a 2m 51s animation:

Short, simple animations to show transcription & translation

Fantastic animated tutorials from McGraw Hill Education – Simple Gene Expression & Protein Synthesis

This will take you step-by-step through transcription & translation and here is a translation animation – short and simple.

In Crash Course Biology #11 – Transcription & Translation, Hank imagines himself breaking into the Hot Pockets factory to steal their secret recipes and instruction manuals in order to help us understand how the processes known as DNA transcription and translation allow our cells to build proteins.
