Getting to Know our DNA

  Secondary | Health | Views: 539

Watch the video from Dr. Giulia, and while doing so consider the following questions:

  • Why does DNA make us all diverse?
  • Where are DNA and chromosomes located?
  • Describe the human genome.
  • Explain how humans are mostly identical, defining the percentages and reasons why.
  • Create an annotated diagram of DNA, based on Giulia’s description in the video.
  • Add functions to your diagram as described.
  • Name the nucleotides that can bind together – there are only certain possibilities. Use the Base Pair Rule.
  • List some of the conditions that come as a result of ‘mistakes’ in the sequence of DNA, chromosomes, or genetic disorders.
  • Giulia describes some techniques that are used in diagnosing mutations in genetics. Research any of these which interests you.
  • What is DNA sequencing? Name the famous scientist linked to the DNA sequencing process and describe his contribution.
  • List some of the applications of DNA sequencing. How does the process help in creating bespoke medicines and treatments?
  • Create a case study, outlining the process from DNA sequencing, to the creation of a bespoke drug, to how this drug treats the condition.
  • DNA can also be used in forensics – what process takes place to extract DNA and how does this help determine a guilty suspect?
  • Another forensic application is ancestry – DNA analysis lets us trace back generations. How does this work?
