What are three structural differences between DNA and RNA?

Function of DNA and RNA:

DNA and RNA are both a type of macromolecule called nucleic acids. Nucleic acids are made of the monomer nucleotides and are important for storing genetic information in the cell.

The Genetic Code:

  • The genetic code of all living organisms is stored in its DNA. This code is used to create all of the other molecules a cell needs, or enables the cells to obtain these molecules from food sources.
  • Before the genetic code can be used, it must be transcribed into usable sections of RNA called messenger RNA (mRNA).
  • mRNA is then read by ribosomes to create strings of amino acids that can then become proteins, or become part of a protein.
  • Specialized proteins called enzymes are those that are used to copy DNA, make mRNA, and perform many other cellular functions.
