In this video, I take you through the structure of DNA. We explore what is meant by complementary base pairing and why the DNA polynucleotides are antiparallel. I then show you how to calculate the proportions of the different nucleotides in DNA. Finally, we look at the structure of RNA and the key differences between RNA and DNA.
