There are no more basic or fundamental building blocks of the body than DNA and RNA. When you want to know who we are as human being, you have to look to these to nucleic acids. These two players, DNA and RNA make sure that the body knows what it needs to do and how to do it. If these two pieces do not cooperate, then none of us live.. All of this I learned at the website, DNAandRNA.com.

One vital piece of information that you will learn from the site is that DNA "carries the vital genetic codes that dictate how an organism will grow and shape. Each DNA molecule consists of two long strands that are wrapped around each other. Because of this, the DNA structure resembles a double spiral 'staircase' or a helix." There is more about DNA listed on the site than I had ever known and I'm happy to have read it.

If this area of science is the least bit interesting to you, then this is a site you need to visit. The information you will acquire will be a great start to enhancing what you can confidently say you know.
