D.N.A.

Deoxyribonucleic acid is a word,
as large as the influence it casts upon the Earth.
More precisely, it fits nicely, as an acid, based,
in creatures big and small, it is the blueprint, how they're made.

The RNA is information carried in your genes,
it's found within the DNA that makes up you and me.
A Double Helix is the name of the shapely pattern,
that DNA will tend to make, it resembles a ladder.
The lines on the outside are two and are a crucial glue,
to hold the sides Nucleotides, a sugar phosphate group.
To each of these there are attached a molecule, you see,
Adenine, Thymine, Guanine, Cytosine, 

Every part of you is made of cells you cannot see,
you could say the DNA is like a recipe.
This double helix ladder can easily unwind,
and wind again, it happens every time a cell divides.
Inside a cell, the DNA strands wrap up real close,
and organize into an x, behold, the chromosome!

Eukaryotic organisms like animals and plants,
use the nucleus of cells to store these precious strands.
-Of course there are so many places DNA is found,
Prokaryotes, like bacteria, spread it all around! 
RNA is like a copy of a given strand,
and essential for an organism to expand. 
In order to expand, the cells will have to split in two,
and once they do, the one that's old will be the same as new.
To achieve this feat a DNA strand must have proteins,
different binds of different kinds can all effect the coding.

DNA has shaped the way all life has evolved,
it is the blueprint, how we're made, creatures big and small.
Deoxyribonucleic acid is a word,
as large as the influence it casts upon the Earth.
It made me what I am, and it made you be you,
now show DNA what YOU'RE made of,
and that you have some big plans to!
