There is a lot of things to know about DNA structure. First of all, DNA is made out of nucleotides. Nucleotides contain of deoxyribose sugar, phosphates, and a base. Everything is identical except the bases. There are four bases: adenine, thymine, guanine, and cytosine. They are often represented by the first letter of their name - A, T, G, and C. A and T are always paired up, while G and C are paired together. These are called "base pairs." The structure of DNA is in a spiral form, known as double helix. On both sides of DNA, there are the nucleotides and in the middle are the based pairs held together by H bonds. I actually had the experience to see and build DNA structure in science class. It was very cool because I was able to actually see how it works. I plan on learning more about DNA structure.

I agree with our blog post. You did a good job on it, and you also made it easy to understand the topic. Word of advise all ways make sure to have everything the assignment wants you to have.
