51. Gene Technology 4 of 6

Genetic technology refers to the artificial manipulation of DNA and genes. This video looks at the tools and techniques involved in genetic technology.
The tools include genetic scissors - called restriction enzymes, a genetic joining enzyme called ligase, as well as the use of DNA probes to show up and mark different sequences of DNA.
We then look at genetic techniques - how to make lots of copies of DNA using the polymerase chain reaction; how to sort DNA fragments according to size in electrophoreses; then how to take this further and make it usable using the Southern Blot.
Finally we look at some of the tricks that can be done using these tools and techniques - such as DNA profiling and fingerprinting; how to sequence DNA - from a molecule to a letter code we can interpret; and finally we look at how cloning genes and the use of recombinant DNA technology allows us to mix the DNA of different species together.
Lots of information. Always a joy.

I listened to these series with earphones and i must say the coughing fits got me a bit startled(no excuse me said afterwards either).On the whole though,good presentation.

[dakanister23]

umm yea urpretty bad ass

[mjaw92]

your are AMAZING! hv got my exams soon and i couldnt understand anything until i came across your vids, thanks alot :)

[kzapeta]

thanks a lot. u rock.

[lgadzik]

thank you!

Since we are all human, how different or similar is the DNA between us. What's the chances that a restriction enzyme cuts in all the same spots?

good stuff
