DNA Model
Just like the model I made, DNA has a spiral ladder kind of look to it the shape is called a double helix. The backbone of DNA is made of alternating sugar and phosphate, in my diagram the yellow licorice represents the backbone. The rungs are made of four kinds of nitrogen containing bases. There is Adenine (A), Thymine (T), Guanine (G), cytosine (C). In my model A= Yellow C=Pink G=green A=orange. Bases of DNA always pair up in a sertain way. A always pairs with T, C always pairs with G. This way the message on both sides of the DNA molecule are mirror messages. This activity did help me understand DNA molecules. I know understand how the colour of the basses work.
