Letter to a friend
Dear Kiana,
I’ve done an experiment that was very interesting and fun in biotech class. What i did in this
experiment was extract my very own DNA in order to make a DNA Necklace. DNA is a
Deoxyribonucleic Acid and what it does is store genetic information. The structure of DNA is
two
molecules that are organized into a ladder called the Double helix. Each molecule is made up of
millions subunits called Nucleotides.
The Phosphate and sugar molecules form the spine of the DNA molecule. There are three bases
that form the rungs which are made up of nitrogen. There are four Nitrogen bases which are
called
Adenine, Thymine, Cytosine, and Guanine. These bases can bond with other specific bases.
DNA is found in the nucleus of cells. DNA is also made into structures called Chromosomes. A
Gene is also found in a section of the DNA that carries information to make up the Proteins.
Now
that you know the basics i’ll start to get into the procedure of the experiment.
The first thing we did was use a 15 ml tube that had 3 ml of water to put in our mouth to swish
around and gently chew the inside of our cheeks for 30 seconds to get epithelial cheek cells. N...
