Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms. The main role of DNA molecules is the long-term storage of information and DNA is often compared to a set of blueprints, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.

DNA stands for Deoxyribonucleaic Acid
It contains the genetic information of how to build the body gentically. One half of this DNA from the male is passed on to the offspring (or scientifically, zygote) and the other half from the female. This is why our features are like our children's.
Eg. A father has black hair...this gene can then be passed down to his child and the child will have black hair too!
Hope that helped!

Deoxy-ribonucleic acid.
They are coding materials made up of 4 distinct bases (segments). A, G, C and T (alanine, Guanine, Cytosine and Thymine). The link together to form a chain which coils further to form a double helix. The arrangement of the chain (E.G AAGCCT) encodes for different amino acids and protein production.
DNA is a collection of such bases to form a code of millions of codons long. the arrangement of this chain dictates physical traits by protein production and enzymatic production.

Here are some basic sites that can be used as teaching aides. http://www.dnaftb.org/dnaftb/1/concept/
'The Cartoon Guide to Genetics ' by Gonick is excellent.

deoxyribonucleicacid.
the genetic blueprint of who we are. It's our genetic fingerprint.
