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.
