Chapter 3  Nucleic acids

From AQA: "Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are important information-carrying molecules. In all living cells, DNA holds genetic information and RNA transfers genetic information from DNA to the ribosomes".

DNA and RNA are molecules that spring up in 4 or 5 different chapters! This chapter gives you an introduction to them, the difference between them and how DNA replicates itself... amazing stuff!

At the end of this chapter, you will also learn about ATP, properties of water and a few functions of inorganic ions.
