DNA Replication Song



depois da PCR Song aqui temos a "DNA Replication Song"


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
