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