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

  1. I’m impressed by that genome machine. It reminds me of the movie Gattaca, they had these genome booths, that would give you a print of your DNA. That is bizarre, regardless its a useful technology, and can be used for good. Determining harmful mutations, etc. Or it can be used for genomics? I think that’s what it’s called. Very odd.

  2. It is impressing where science has got to. DNA cloning is here, and with this can come the possibility of bringing back extinct animals. Scientists have been studying this possibility to bring back a wooly mammoth. I believe this is all possible thanks to fossils and better yet, frozen animals that can serve as frozen DNA.
    This link talks about the cloning of the mammoth.

  3. It is amazing what science has reached. Many say that dan cloning is finally within our reach and that it is a good thing but is that the truth? A few weeks ago a classmate and I discussed with Mr. Adrover if this was the really a good thing and yes it may lead to some good advances in technology, medicine and science but the pros and cons are going to listed and the cons list is a long one. What if we were to “revive” a Neanderthal? What will it do in our modern world? Will it be good for the world to accept two different types of humanoid beings? Will it survive?And will it bring some new diseases? I ask myself these questions because it is not only the Neanderthal what we can “revive” there are a lot of other species many of us want to see come back to life. My opinion that this is unnatural and yes we may use cloning for good things but there are also horrible things that can come of this. DNA study is awesome but the advances it may come to see may also harm us and Earth because if something is extinct then it is supposed to STAY dead.
