If restrictive enzymes test for certain base sequences, why would the same sequence appear again and again in the DNA? Wouldn't there be other sequences? Or does the same sequence repeat? Also, why do you use one restrictive enzyme, why not a lot of them to get a much closer match? Sorry Leslie, it's a little confusing!
Wow this is so cool. It would be so awesome if we actually got to try it! Now I can brag to my mom how I know (as in I can explain it!) how they test DNA on TV shows.
thats really cool how they seperate dna that must be really cool to watch. i wonder who invented Gel Electrophoresis i like it when the dna splits and the small and large pieces move at different rates.
I found an article in the New York times a couple days ago about how scientists are starting to decode whole genomes to find the source for diseases and which parent they are from, and it showed a picture of a Gel Electrophoresis. I realized that what we are learning about Genetics is actually used in everyday life. Here is the link to the article: http://www.nytimes.com/2010/03/11/health/research/11gene.html?scp=1&sq=scientists%20decode%20whole%20genome&st=cse
This was really awesome! I wish that this could be one of our labs so we could REALLY get to do it our selves. I dont really understand how to compare the DNA after you see the image though. Also, I think micropipettes are really cool. HAHA :) Thanks!

thats so cool
ReplyDeleteman this is awesum, pipettes r really funn to use btw!!

ReplyDeleteits so cool how this works! Now i understand how they do those dna tests at crime scenes;) Thanks Leslie!!!!!
ReplyDeletethis is cool
ReplyDeleteThat's so cool!
ReplyDeleteI finally understand it!
What would we do without science?
(and junk food):0 <3<3
yum yum...
Sorry... I was hungry...
But yeah... it helped!
Thanks Leslie!!

ReplyDeleteThanks so much Leslie!

This was pretty cool. I think it was helpful too.Thanks Leslie
ReplyDeleteThis is a very educational animation, it helped me understand Gel Electrophoresis in a deeper way! Thanks Leslie!
ReplyDelete-I agree with Michael!!

that was really cool and helped me a lot! i now understand how they use DNA test on those crime shows!!
ReplyDeleteThis helped me understand Gel Electrophoresis much better
ReplyDeletethank you Leslie
