7.3 Translation

BioKnowledgy Presentation on 7.3 Translation (AHL) from Chris Paine.

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

Click on ‘tRNA’ to work through an Interactive Tutorial from Wiley.

Fantastic animated tutorials from McGraw Hill Education – how Translation works, Translation Initiation, Translation Elongation & Translation Termination.

Paul Andersen 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.

Find a video lesson on this sub-topic at Dan Rott videos, or many assessment statements are 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 4m video here or PCR from the DNA Learning Center (1m 28s):

The PCR song:

MESELSON & STAHL experiment (proof of SEMI-CONSERVATIVE replication)

Great animation from McGraw-Hill.

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.

C14.5 to C14.7 Polymers

Science Bank 11 (Industrial Chemistry): you just need part 2 – Plastics & Polymerisation (from 4m 45s to 10m 20s).The diverse world of polymers (a TED-Ed original from Jan Mattingly):

A lovely site about polymers – lots of information and animations.

Making nylon in the lab.

Here are two short videos on polymers: polythene from RSC (5m 30s) and polystyrene from Lammas Science (2m 15s). And here are three longer ones: plastics/polymers from Science in Focus (18m 40s); polythene from Chemistry in Action (20m) & BBC Short Circuit polymers (& crude oil) (19m).
