7.1 DNA Structure & Replication

Bioknowledgy 7.1 DNA structure and replication AHL from Chris Paine.

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

Click on ‘DNA’ to work through a very detailed Interactive Tutorial from Wiley.

How DNA is packaged (1m 43s):

A DNA replication animation or click on ‘DNA Replication’ to see a more detailed Interactive Animation from Wiley or here are some fantastic animated tutorials from McGraw Hill Education – DNA Replication (in prokaryotes), DNA Replication fork & lagging & leading strands in DNA Replication.

Paul Andersen describes the molecular structure of DNA in What is DNA?. And here, he explains DNA Replication:

Here’s a TED-Ed lesson on what happens when your DNA is damaged

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.

2.7 Replic Transcr & Transl notes to complete (created by Ms Green)

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

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.

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 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

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.
