Life Science Chapter 6 - Song Lyrics

 

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.
