What is the role of DNA

In this video I’ll be looking at that molecule of life, DNA. What it is, how it works and how it relates to life itself. Let’s find out more.
DNA is a molecule made from 2 strands. Each strand is made from many many molecules called nucleotides. Each nucleotide is formed from a sugar molecule, a phosphate and an interesting molecule called and organic base. In the molecule of DNA there are 4 organic bases called Adenine, Thymine, Cytosine and Guanine, and each nucleotide could have any one of these 4 organic base molecules.
I this video I’ll talk about the structure of DNA and how it is used to make proteins. I’ll also talk about proteins and why they are vitally important in biology.
