La sience en chantant.

Quelques vidéos (scientifiques) rigolottes... J'ai rajouté les paroles en bas quand elles ne sont pas sous titrées.






Deox / y-ribo / nuclei / ic-acid / is made from two strands, a double helix

So then, the strands come apart,
Nitrogen bases, they start
to unzip
By DNA helicase

H2 bonds
Between adenine and thymine
H2 bonds
Between cytosine and guanine
H2 bonds
The ladder structure is strongest in
Phosphodiester links

D-N / A Pol-ym / er-ase
Builds the new strand
From the / 5" to 3"
Direction

H2 bonds
Between adenine and thymine
H2 bonds
Between cytosine and guanine
H2 bonds
The ladder structure is strongest in
Phosphodiester links

Now I can see that its replicating
In a way thats quite interesting (YEAH!)
No matter the distance, the leading strand
Is followed by the lagging one

Finally...the ligase
Seals up all the breaks
A new....a new....a new....DNNNNNNNNNNA!
And it starts again!!

Oh, how I love bi-olo-gy (yeah yeah yeah)
It's better than chemistry
And next time I have to go pee (I know)
what's happening inside of me


Les deux qui suivent sont des pubs :



There was a time when to amplify DNA,
You had to grow tons and tons of tiny cells.
(Oooh) Then along came a guy named Dr. Kary Mullis,
Said you can amplify in vitro just as well.

Just mix your template with a buffer and some primers,
Nucleotides and polymerases too.
Denaturing, annealing, and extending,
Well it’s amazing what heating and cooling and heating will do.


PCR when you need to detect mutation (detect mutation)
PCR when you need to recombine (recombine)
PCR when you need to find out who the daddy is (who’s your daddy?)
PCR when you need to solve a crime (solve a crime)


(PCR) To all the scientists out there doing PCR, Bio-Rad salutes you with the all-new 1000 series thermal cycling platform.
