The Molecular Basis of Inheritance

"The key to Ion Torrent's Personal Genome Machine is a semiconductor chip that holds 1.5 million sensors, each of which can hold a single strand DNA fragment. The chip electronically detects the DNA sequence, unlike other sequencing machines that optically detect DNA with pricey lasers, microscopes, and cameras. It can sequence a DNA sample in a few hours, while other machines can take at least a week. And it can scale up fast."

The following videos account for the mayor topics discussed for our tests on March 18 (10H) and March 19 (AP Bio).

Anyone can benefit from any video, but keep in mind that the AP Bio course addresses more details of the DNA molecule. The first two videos are from Crash Course Biology, and account for DNA Structure, DNA Replication, mRNA transcription, and Protein Synthesis. These videos cover the specifics of 10th grade Bio:

DNA Structure and Replication

DNA Transcription & Translation

The next three videos are from Craig Savage. They discuss the same topics of the Molecular Basis of Inheritance, but with a closer look. AP Bio students will benefit more from these videos:

Introduction to Protein Synthesis

Transcription

Translation
