Nucleic Acids

  • Includes DNA and RNA
  • Made up of monomers known as nucleotides
  • Nucleotide is made up of three components – ribose sugar, phosphate group and one of the 4 nitrogenous bases (A, T, C or G)
  • They are found in the nucleus in all cells and encode the genetic material that make up an organism (DNA)

Structure Level Info
Primary structure The sequence of nucleotides that are held together by phosphodiester bonds in a certain order.
Secondary structure The interactions of the two strands of DNA. Remember that DNA consists of a two strands that form the double helix, this double helix structure is held and maintained by the hydrogen bonds that form between the nitrogenous basis between the two DNA strand.
