I can name the monomers of some natural polymers, and understand their importance for life.
Lesson details
Key learning points
- DNA is made from monomers called nucleotides.
- Natural polymers are important for life.
- The carbohydrates starch and cellulose are made from the monomer glucose.
- Amino acids contain two functional groups and can form polypeptides and proteins.
Common misconception
Thinking that DNA is made of a single polymer chain.
Use the slides and a model to reinforce that DNA contains two polymer chains in a double helix structure.
Keywords
DNA - DNA is a polymer with a double helix structure that carries genetic information.
Polypeptides - Polypeptides are condensation polymers formed from amino acids. They contain peptide bonds.
Proteins - Proteins are polymer molecules made from joining amino acids together. They contain one or more polypeptide chains.
Nucleotides - Nucleotides are monomers that join together to make the polymer chains in DNA.
Amino acids - Amino acids are monomers that join together to form polypeptides and proteins.
