C2 Bonding structures.

C2 Bonding structures.

1. biological Polymers

   • DNA is a polymer made from four different monomers, called nucleotides. These join together in different combinations to make long strands. In a DNA molecule, two strands wrap around each other to form a double helix structure.

2. additional polymers

   • Addition polymers are made from molecules containing C=C bonds. Polymers have different uses that depend on their properties. DNA, starch and proteins are biological polymers.

3. polymers- higher

   • Condensation polymers form in a different way to addition polymers like poly(ethene). Instead of just one product forming (the polymer molecule), two products form
