AND DNA

Genes are located on chromosomes
in the nucleus of most cells.
Chromosomes are made of protein
and DNA as well.
DNA has four subunits
known as nucleotides.
And each nucleotide has a sugar,
a phosphate, and a base inside.

The four bases are adenine,
thymine, guanine and cytosine.
Adenine binds to thymine,
while guanine and cytosine bind.
Groups of three code for aminos.
Long strings of amino acids make
proteins which send messages
determining our traits.

Adenine binds to thymine,
while guanine and cytosine bind.

Mutations, caused by mutagens like radiation,
occur when the order of bases
in DNA changes. 

With genetic engineering they
use mutations in a beneficial way
to make desired proteins,
fix damaged genes
and keep diseases at bay

Adenine binds to thymine,
while guanine and cytosine bind.

A deletion mutation is
when a base is left out.
When a base is added
insertion mutations come about.
