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.
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):
