How does DNA store information

The order of the base pairs in a strand is a code that is used to produce proteins

Define nucleic acids

are large nitrogen-containing polymers found mainly in the nuclei of cells

Simple sugars, slightly more complex sugars, and polymers built from sugar monomers are classified as

carbohydrates

Describe a polymer

is a large molecule that forms when many smaller molecules are linked together by covalent bonds

The smaller molecules that join together to form a polymer are called

monomers

Name the three parts of a nucleotide in DNA

phosphate group; Deoxyribose sugar; Organic base

How are starches used in plants

plants store starches for food and to build stems, seeds, and roots.

Name three polymers that can be synthesized

polyethylene, nylon, rubber

Amino acids are the monomers that cells use to build the polymers known as

proteins

Name four types of polymers that are produced in plant and animal cells.

starches, nucleic acids, cellulose, proteins
