Tree of Life Worksheet: homopolymers and heteropolymers (Student)

ZOOMING DOWN THE TREE OF LIFE TO LIFE'S BUILDING BLOCKS EXTENSION: heteropolymers and homopolymers Open the Tree of Life web page. As you go down the Tree of Life, record whether the monomers are the same in the polymers or different.
Macromolecules in the Tree of Life	What is its monomer called? a. Amino acid b. Sugar c. Nucleotide d. Fatty acid	Is the monomer a homo- polymer with only one kind of monomer? Write "1" if it is.	Is the monomer a hetero- polymer with 2-4 different kinds of monomers? Give the number, if you know.	Is the monomers a hetero- polymer with more than 4 different kinds of monomers? Give the number, if you know.
