Chemistry Topic Practice
Natural Polymers: DNA and Proteins | GCSE Chemistry
Living organisms produce complex natural polymers like DNA, proteins, and starch.
What are the monomers that make up a protein chain?
What is Natural Polymers: DNA and Proteins | GCSE Chemistry?
"Naturally occurring large molecules made of repeating units, essential for biological structures and functions."
Life's Molecules
DNA: Two polymer chains made of four different nucleotides in a double helix.
Proteins: Polymers of amino acids.
Starch and Cellulose: Polymers of glucose.
These carry genetic information or provide structural support.
Exam Tip
Biology Link: DNA stands for Deoxyribonucleic acid and is essential for all life.
