Many assessment statements are also covered by Stephanie Castle (with more being added all the time).
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 here; and from the DNA Learning Center (1m 28s):
The PCR song:
MESELSON & STAHL experiment (proof of semi-conservative replication)
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.
