Deoxyribonucleic Acid

DNA

Jennifer. J. Farr


What is dna
What is DNA?

It is the genetic material that makes up all cellular organisms and most viruses.


Where do you find dna
Where do you find DNA?

In the nucleus of every cell in a living organism.


Does dna have a special job
Does DNA have a special job?

It is a molecule that provides instructions (blueprints) for building different pieces of a cell.


What does a dna molecule look like
What does a DNA molecule look like?

It takes on the form of a twisted ladder shape that scientists call a “double-helix”


Why are the rungs of the double helix of the dna different colors
Why are the rungs of the “double helix” of the DNA different colors?

Each color represents a letter of the DNA alphabet:

A, C, T, andG


Why are the rungs of the double helix of the dna split
Why are the rungs of the “double helix” of the DNA split?

The DNA alphabet letters bond together:

Aalways bonds withT

Calways bonds withG


What do the letters of the dna alphabet represent
What do the letters of the DNA alphabet represent?

A = adenine

T = thymine

C = cytosine

G = guanine

These are all called BASES


Click on the Double-Helix to go to a web site where you can build a DNA strand that contains five base pairs


Now that you have learned a little about dna why not watch an interactivemovie that features dna
Now that you have learned a little about build a DNA why not watch an interactivemovie that features DNA?

(Click on this bag of popcorn to view the movie.)


Now that you are a build a DNA expert it’s time to explore some web resources that feature DNA and the role DNA plays in genetics.

Click on the Genetic Science Learning Center logo to access their web site.
