• DNA determines what proteins the cells produces so determines what type of cell it is gonna be
• what is a genome?

  The complete set of genetic material in an organism.
• why is it important for people to understand the human genome?

  -allows scientists to identify genes that are linked to diseases

  -can develop effective treatments for research
