DNA is a natural polymer that consists of hundreds of millions of repeating units called <em>nucleotides</em><em>.</em>
Hair protein consists of long chains of <em>amino acid</em> repeating units.
The rubber in car tires is a mixture of natural and synthetic rubber. Natural rubber consists of long chains of <em>isoprene repeating units</em>. In one type of synthetic rubber, the repeating units are <em>butadiene and styrene molecules</em>.
