7.2 Transcription & Gene Expression

7.2 transcription & gene expression from Bob Smullen

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

Fantastic animated tutorials from McGraw Hill Education – transcription and translation and Exons & Introns.

Control of Gene Expression

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.

Epigenetics: epigenome: the symphony in your cells, a 5m video and here is Epigenetics from Learn.Genetics.

2.7 DNA Replication, Transcription & Translation

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

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

DNA REPLICATION

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.

PCR (the POLYMERASE CHAIN REACTION)

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. 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 4m video from Mr Andersen on the Meselson-Stahl experiment or from Youreka Science the most beautiful experiment in Biology (7m 33s).

TRANSCRIPTION & TRANSLATION

Transcription & translation, a 2m 51s animation:

Simple Gene Expressionanimated tutorial from McGraw Hill Education

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.
