Worksheet: Polymerase Chain Reaction

In this worksheet, we will practice describing the steps involved in the amplification of DNA by polymerase chain reactions within a thermal cycler.


What polymer is the genetic code of all plants and animals composed of?

  • APolysaccarides that consist of pentose sugars forming carbohydrates
  • BPolyamides called DNA and RNA, which contain nucleic acid bases in the repeat units
  • CLipid polymers that contain nucleic acid bases organized in three-unit sequences
  • DPolymers of nucleic acid bases with phosphoric acid to give complex polyesters abbreviated RNA and DNA
  • ENatural polyamides making up collagen, proteins, and peptides
