DNA (deoxyribonucleic acid) and other naturally occurring polymers


  • DNA (deoxyribonucleic acid) is a large molecule essential for life. DNA encodes genetic instructions for the development and functioning of living organisms and viruses.

Most DNA molecules are two polymer chains, made from four different monomers called nucleotides, in the form of a double helix. Other naturally occurring polymers important for life include proteins, starch and cellulose.

Students should be able to name the types of monomers from which these naturally occurring polymers are made.
