DNA Origami

DNA stands for deoxyribonucleic acid. It is a long thin molecule made up of things called nucleotides, sometimes referred to as bases. There are four different types of nucleotides: adenine, thymine, cytosine, and guanine. The nucleotides are represented by their first letter: A- adenine T- thymine C – cytosine G – guanine. The nucleotides pair up and are called base pairs. These base pairs form the middle structure of our DNA strand (the parts that look like rungs on a ladder.) Only certain nucleotides can pair together: A only connects with T and G only connects with C. The outside of the structure holds the DNA strand together on both sides while twisting. The shape it makes is called a double helix.

Lets make a double helix out of paper. You can get the file here.
