Lesson Title: Today we are learning about
How are DNA and polymers linked?

Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding

Success Criteria:	You will show your learning by...
Students should be able to name the types of monomers from which these naturally occurring polymers are made. (HT only) Amino acids have two different functional groups in a molecule. Amino acids react by condensation polymerisation to produce polypeptides. (HT only) For example: glycine is H NCH COOH and polymerises to produce the polypeptide (-HNCH2COO-) and n H2O. (HT only) Different amino acids can be combined in the same chain to produce proteins. (HT only) DNA (deoxyribonucleic acid) is a large molecule essential for life. DNA encodes genetic instructions for the development and functioning of living organisms and viruses. (HT only) Most DNA molecules are two polymer chains, made from four different monomers called nucleotides, in the form of a double helix. (HT only) Other naturally occurring polymers important for life include proteins, starch and cellulose. (HT only)

AFL/Key Questions:

(Chem only) What are the monomers that form the following naturally occuring polymers? 1. proteins 2. starch 3. cellulose
(HT only) The monomers that form the naturally occuring polymers are: 1. proteins = amino acids 2. starch = glucose 3. cellulose = glucose
(Chem only) What type of polymerisation reaction occurs when amino acids react to form polypeptides? (Include a reason why)
(HT only) Amino acids react by condensation polymerisation to produce polypeptides, this is because amino acids have two different functional groups in one molecule.
(Chem only) What would the equation looks like for the polymerisation of glycine?
(HT only) n NCH COOH --> [-HNCH2COO-]n H2O.
(Chem only) How are proteins an example of a condensation polymer?
(HT only) Proteins are an example of a condensation polymer because Different amino acids (with two functional groups) can be combined in the same chain to produce proteins.
(Chem only) What is DNA and what is its function?
(HT only) DNA (deoxyribonucleic acid) is a large molecule essential for life. DNA encodes genetic instructions for the development and functioning of living organisms and viruses.
(Chem only) Why is the structure of DNA described as a polymer?
(HT only) Most DNA molecules are two polymer chains, made from four different monomers called nucleotides, in the form of a double helix.
(Chem only) What are the other naturally occuring polymers that are important for life processes?
(HT only) Other naturally occurring polymers important for life include proteins, starch and cellulose.

Remember to check for PROGRESS

Starter Activity	Differentiation and Challenge question/task
Students to copy and complete the keywords. Teacher reveals missing letters; Students correct mistakes; Discuss the scientific meanings of the words. Students to write down the definitions of the most important / new keywords. Discuss the 'Memory Anchor'. What does it show? How does it relate to the what we are learning about today (title)?

Think about PACE – Develop, consolidate and deepen knowledge, skills and understanding
