Biological polymers

Question 1

biological polymers

Answer 1

naturally occurring condensation polymers

Question 2

structure of DNA (deoxyribonucleic acid)

Answer 2

• found in the nucleus of cells
• ‘double helix’ structure
• polymer made from monomers called nucleotides
• four different types that contain different ‘bases’
• abbreviated to A, T, G, and C
• join together in different combinations to form long strands

Question 3

structure of proteins

Answer 3

polymers made from monomers called amino acids

each amino acid has two reactive functional groups, allowing many amino acids to bond together to form a protein

-amino acids join together in different combinations to make long strands, which then fold into complex shaped

Question 4

structure of starch

Answer 4

polymer made from glucose monomers

-contain many glucose monomers joined together in long chains with branches
