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):
